Thanks for the info! Here are the three saved files and the autosave. The most recent crash took place last night right after the autosave, when I had ended the turn and the Asturian rebels sallied out to attack my army on the last season of the siege. I got as far as the battle screen, where I selected "Fight battle on battle-map," and right after that the game crashed. My guess is if you are kind enough to check these files, you probably will not encounter the same crash, but rather one later on. Typically that's how my games worked; I would re-load the previous save and get past the CTD with no problem, only to have another one later on. Typically, the longer I played, the more i could count on a CTD happening. As I said before, however, there is no pattern as to when these CTD's occur. They happen on the end-turn, right before a battle, and right after a battle, and that one right in the middle of a turn. If you could give me any advice as to what is wrong or how i can fix this, i would be incredibly grateful. I have never had a complete EB game thanks to CTD's, and my limited software tech knowledge inhibits me from doing much about it.

p.s.-not sure if i should use a "password" with these files, i didn't know if that would be helpful or not
