I ran into problems like this WITHOUT the trainer..
at any rate, most problems like this can be fixed by turning off the Battery option (if you think it is a trainer problem), and clicking on LAST CHECKPOINT in the MENU OPTIONS from ESC key.
Thanks Cal for the pointer. Will do that as suggested and feedback on the result.
Yes you have right. I have test the game and i confirm what you tell. Sometime you need to turn off unlimited battery to make an action. But the trainer don't crash the game or don't make bug the game. All work perfectly.
Thank you to your work Cal !
Well I can say that I've taken care of my crashing problem. Not only have I cranked down the video settings in the game but I have set my machine up to do a clean boot. So far I have not had any crashes.
