At the bottom of the page there is a comment section where you can let others know which step fixed your issue or to let us know if you are still having issues, make sure to give us as many details as you can including what error code and message you receive.

1. Verify Your Game Cache

With most issues you come across in Counter-Strike: Global Offensive can be fixed by verifying your game cache using the Steam application. This checks your game files for anomalies in files downloaded from the Steam server. It commonly fixes issues regarding missing models, game crashes and purple checker boards on models inside a map.

Instruction Guide:

  1. Open the Steam Application.
  2. Click on the Library tab.
  3. Right click Counter-Strike: Global Offensive.
  4. Select Properties.
  5. Press on the Local Files tab up the top.
  6. Press on the “Verify integrity of game files” button.
  7. Wait for a pop up to appear with the text “All files successfully validated”.

After this has completed Steam will download the missing files before you are able to launch the game. You can track the download on the downloads button at the bottom of the Steam application. You are able to do this step on any game downloaded with Steam, so keep this guide in mind if you are having issues on other games and their maps.

2. Turn on the Download Filter

There is a chance that you have accidentally set Counter-Strike: Global Offensive to not download any maps if you are trying to join a community server. This can be fixed easily by enabling it again using your developer console inside of Counter-Strike: Global Offensive and can be changed again after you have downloaded the map or files required.

Turn on your developer console and type in the following:

cl_downloadfilter all

Make sure to press enter after typing it in. There are some other parameters that you can place at the end of this command to prevent the game downloading maps and files to your computer. If you are getting errors you should not use these commands but they are good to know when everything is working correctly. These commands are:

  • cl_downloadfilter none – Disable all files from downloading
  • cl_downloadfilter nosounds – Disable downloading sound files

3. Download the maps and add them manually

The first place to try and find a missing map is on the Steam CS:GO Workshop, you can click the link or access this while in the game by pressing shift + tab, clicking on the “community hub” text and pressing on the “Workshop” tab.

Search the map name or the file name of the map you are missing. It may not come up right away as the name of the map on the workshop may be different then the map name. You best bet is to try to find the file name which will be in the following format: GameMode_MapName_Version. The version is important on community maps as the same map can be altered by multiple people and re-uploaded.

Taking the offical Dust 2 as an example these are what you would want to search the following to try and find the map:

  • dust II
  • dust 2
  • de_dust2

If you cannot find the map you are after on the workshop you will want to find the map online and place it in the CS:GO maps folder. The two common places to find maps that are not on the workshop are GameBanana and GameMaps.

After downloading a map you will need to place it in the correct folder. The default location on your computer for CS:GO maps is:

C:\Program Files (x86)\Steam\steamapps\common\Counter-Strike Global Offensive\csgo\maps

4. Remove game from the Windows Data Execution Prevention

If Windows at some point considers Counter-Strike: Global Offensive a threat to the computer in which it believe any files downloaded from it to your computer may contain viruses or malware it may be placed in the Data Execution Prevention. Luckily as long as you have an administration windows account you can remove it.

To start open the Control Panel which can be found in your Start Menu or by searching “Control Panel” in your windows search bar.

Windows 10 and Windows 7:

Control Panel -> System and Security -> System -> Advance system settings -> Settings -> Data Execution Prevention

Once you have the window open make sure that Steam.exe and CSGO.exe are not listed. If they are select them and press the remove button. In addition if you notice you cannot download any files onto your computer from third-party software make sure that the option for Data Execution Software is only on for the programs you choose which is the bottom radio button.

Make sure to hit the apply button the the very bottom of the window once you are done.

Though this has been reported by multiple CS:GO players as the reason they are unable to download or play certain maps it may be wise to invest time into understanding what caused the game to end up here. I would suggest creating a back-up of your files and running an anti-virus or malware scan. Windows Defender is a good start but Malwarebytes an addition security software does not hurt. They also have a free version.

5. Change Internet Explorer Security

Internet Explorer – Internet Settings

Although Microsoft has changed to Microsoft Edge as their browser you will still find Internet Explorer located on your computer as long as you have downloaded it. Some software use Internet Explorers settings as a guide on where to download items and which security settings to follow, of course if you are on a MAC you can skip this section.

If you uninstalled Internet Explorer you can find the download on the Microsoft website, as if writing this the latest internet explorer is Internet Explorer 11 which is the second or fifth option on their website. Download the version which is correct for you, if you are unsure open your system setting and check what “System Type” you have. Both x86 and x32 use the 32-bit version while x64 used the 64-bit version.

Once it is installed or you have opened it, press the cog in the right hand corner and open the Internet Options. Then navigate to the Security tab and lower the “Security level for this zone” to a maximum of Medium-high. If you are still having issues I would try again at only at medium.

Do not change to a custom level unless you know what you are doing. It is not needed for this guide at all for downloading or fixing CS:GO map error.

6. Remove the maximum download size launch option

If you have copied and pasted launch options without reading what they do you may have accidentally limited the allowed size of each download in Counter-Strike: Global Offensive. This is easy to check and can be fixed by removing some text in your launch options.

Just like in the first step of this guide open the Steam application, navigate to the Library and right click on Counter-Strike: Global Offensive. Select Properties again but this time stay in the General tab which is the default tab when the properties window opens. Click on the “Set Launch Options” button in the middle and check the make sure you don’t have the max download file size parameter placed inside of the text box.

You can do this by searching for and removing “-maxdownloadfilesizem ” with the number after it.

For example:

-maxdownloadfilesizem 1024

7. Uninstall and Reinstall the game

The very last option takes the longest to do, and that is to uninstall Counter-Strike: Global Offensive and install it again. Make sure you have done every other step above before you do this.

Uninstall Counter-Strike: Global Offensive steps:

  1. Open the Steam application.
  2. Navigate to the Library using the Library tab on the top of Steam.
  3. Right click on Counter-Strike: Global Offensive.
  4. Press on the Properties option.
  5. On the pop-up click on the Local Files tab up the top.
  6. Click on the Uninstall Game button.
  7. On the Steam library an overlay will appear asking you to confirm the uninstall.

Install Counter-Strike: Global Offensive steps:

  1. Open the Steam application.
  2. Navigate to the Library using the Library tab on the top of Steam.
  3. Right click on Counter-Strike: Global Offensive.
  4. Press Install.

Now that the game has been uninstalled and reinstalled open the game and try to play on the map you where having issues with. If it is a custom map it will need to download again from the community server while official maps do not need to be downloaded as they come with the installation.

8. Other Hardware Issues

If the map is a community made map with a lot of models your computer or laptop may have issues drawing all of the models on the screen. In this case you will need to upgrade your hardware which is way beyond the scope of this guide. Usually if this is the case you will get error message or box once the game crashes which you will be able to look up and confirm this for yourself.

If you are experiencing textures flicking black or models in the game flying across the screen usually making long triangles it means that your graphics card is faulty. This issue is commonly experienced after you install a new graphics card as the issue comes from the manufacturing of the card and needs to be send back with warranty for a new card. Before you send the graphics card back though make sure you have the correct graphics driver installed and any old graphics cards have their drivers uninstalled.
