CSGO (Counter-Strike: Global Offensive) is arguably one of the
most iconic FPS titles of its generation on Windows.
SGO is frequently updated by its publisher Valve, but it
appears that a recent update is causing the game to crash with
“Pure Server: client file does not match server” error.
The update has introduced multiple changes for the “sv_pure
servers”. It has been updated to kick players in official
matchmaking if they load asset files into game memory from
files that are not present on the game server filesystem.
Unfortunately, this change in CSGO update has resulted in a
widespread problem. According to various reports and our own
testing, players are getting kicked from the competitive and
official matchmaking after applying the update.
After a user is kicked from the game, the following error
message is displayed:
- Pure Server: client file does not match server
If you are getting kicked because of this, there appears to be
an easy workaround but it requires you to download up to 256
files after validation.
How to fix Pure server error in CSGO
- Restart your computer and close Steam.
- Open File Explorer.
- Navigate to Program
- Make a backup of two folders—models and materials if you
have custom stuff/configurations for models, sprays, etc.
- Select both folders and press & hold Shift and hit the
Delete key to permanently delete your Models and Materials
- Open Steam and head to the Library section.
- Right-click on CSGO and select Properties from the menu.
- Go to ‘Local files’ and click on Verify Integrity of Game
Steam will verify the game’s files and their servers will
notice that you have deleted 256 files from models and
During this process, deleted files will be reacquired and it
may take several minutes before you can launch the game again.
