If you are currently running Windows 7 and cannot play a game that is currently using Gameguard as an anti-hacker protection system then read on. If you have this problem there are some fixes that can help you play again:

1. Delete the gameguard folder in the game folder. Then run the exe for the game and gameguard's update system will replace the gameguard folder. (Back the gameguard folder up just in case)

2. Use the following link and replace the gameguard.des in your game's main folder not the gameguard folder. (Back up just in case)http://en.flownyx.net/GameGuard.zip

3. If all else fails then try to fresh install a x64 Windows 7 system. This will delete all former data so back up what you need.
