Hi ccliffy
Try verifying your installation for any errors via steam ...
Go to your steam library and right click on GameGuru...Select "properties" .....then select "local files" and finally "verify integrity of game cache"
See if that brings anything to light and fixes your issue .. .
You could also try setting Game Guru to "Run as administrator " see if that helps .....
The only person ever to get all his work done by "Friday" was Robinson Crusoe..
