I appreciate everyone's feedback on the trainer. We're looking into the issues and I'll update everyone here when I have more info.
I would like to know if anyone else is experiencing any actual slowdowns when the trainer is loaded. I personally don't notice any difference and wonder if it may be a particular configuration.
I played for two hours with the trainer and experienced only one slowdown that lasted about 10 seconds... and I didn't get the impression that it had anything to do with the trainer.
I've used all the functions of the trainer except "one hit kill" and everything has worked perfectly.
Game is pretty fun...
