i also recall that in mtw there was a problem with corrupted campaigns. once the campaign file was corrupted, it couldnt be fixed and would crash at the same point every time thereafter. i forget if stw had this problem too (it's been a while), but you might try starting a new campaign and see if that works ok.

also, if Red Harvest shows up here to post, i'm sure he'll tell you to never save the game right before the end of your turn and to always save right when your turn comes up to play. i never had this problem, but he swears by it.
