patcher_cf.exe

Patcher_Cf.exe is not the update for Gameguard, thats the Update for Crossfire
If you want to update your Gameguard, just delete the Gameguard folder in your Crossfire directory.
It will be automatically be repatched the next time you'll start your Game.
If that doesnt work properly, you can reinstall your Game by downloading the Setup from the Mirrors and Alternative Downloads on the Website. If these dont work for you, you can try it with this Mirror.

thanks..much appreciated
