Guys, I've been playing FC4 the last 3-4 days and I've had no problems at all with the trainer. I run it then run the game then wait for 1-2 minutes after I start the game to activate the trainer and options. I've had no problems with the trainer.
Edit: I just finished a 4 hour session in the game using the trainer without a single issue.
