The trainer frequently crashes the game for me, running Win7 64
Update the game to ver. 1.1 and it'll work fine ...
Read Trainer description ... it says "WRITTEN FOR THE PATCHED (1.1) RETAIL VERSION OF THE GAME"
I hope this solve the problem ...If not please Check this link www.cheathappens.com/trainer_troubleshooting.asp
Good luck and have Fun ...
