All I can suggest is uninstalling and reinstalling the game, but that's not necessarily going to solve anything. You might be best emailing Steam support on this one. You might have to wait a while for a response, but you'll at least get some more helpful advice.
I'll try starting a new game tonight, without the trainer, and see if it changes anything.
