When you will play show when GameGuard is on you cant play restart you computer or innstall the game aigan then its must go
- ok restart your computer, this always happens to me after a patch
- you hak your using is patched and game guard (gg) deteced it
- and if now working still then you will have to re-install your crossfire
- if still got the same problem and no one knows here post this in the help section on the forum
yes restart ur comp or reinstall the game as every1 said that should work but u shoulda posted in help section but idk
if none of the above works, uninstall cf, delete (if any) trace files and folders connected to it, then run ccleaner (both file cleaner and registry cleaner), then reinstall crossfire, hope i helped
