If you're experiencing crashes when trying to load a saved game, and this happens regardless of whether it's a new or existing save, this may be the result of having special characters in your Windows username (such as accented letters).
To see if this is the reason your game is crashing, try creating a new Windows account on your machine that does not have any special characters, and then launching the game using that account.
