The Trainer also not working with me. I have the Stream copy updated today (11/25/2011) am opening the trainer as admin then the game and as soon as enable the trainer (F1) a wholoe bunch of writting appears in top of the game, Asuming the trainer is accessing the game files because i did read the stream game directory on my system. I try to take a screen shot but won't work. In fact as soon as i enable the trainer and all that writting appears the game freezes..
Just tried the new trainer - decided to start fresh and start a new campaign. With the trainer on, game crashed on choosing the starting level. The crash also inactivated the mouse pointer, with a hidden dialog on the desktop - had to go into Task Manager and end it manually to recover.
