I have recently upgraded my systems from XP to vista. I tried to reinstall this game and it all worked out fine but then I went to play it and the games is running kinda slower than before I have exited all programs that I could (Anti viral and junk like that) and the game is still running slow.
maby you need to get a faster system because upgrading can sometimes slow down your comp speed
Try turning all of the graphics down to the lowest
most games require a faster computer to play in Vista
Hmm just wondering would putting the computer in safe mode do anything to the game or the compatiablty icon under the properties
