Try to delete some of the save games you have, if you have to many might cause crash to desktop
uh dude.. WHAT saves? some of us cant even play it..
Hmm, verify game cache (@ Steam) and don't load up in Continue Campaign (Auto-save) but from the last normal save you made.
I actually tried both options, but none worked. Anyway, since the game crashes even without trainer, that is up to the developers of the game to solve the problem. I paid the money for the game and I want it to work normally. Otherwise, this will be the last Total War game I have ever bought.
