Game crashes when you use the trainer.
Where did you buy the game? Can you zip/rar your game exe and attach here or upload to a file sharing site and PM me the link?
Are you using the latest STEAM version in DX10 mode?
I'm having the same issue, DX10 latest STEAM version. CTD is always 20 seconds or less from trainer activation. Checked Steam downloads before posting, the game had a small update in the last few days, might have broken the trainer.
