Been away from Guild 3 for a few months but I've had steam do auto updates. When I went to go play one of my saved games, The game launched but one click and the game crashed. Tried this three times with the same effect. Thinking the saved file some how got corrupted I went to a different saved game. Same thing. Then I just let the intro run, selected the game and without so much as clicking anything, the game crashed. What to do?

My guess would be that your save is not compatible with the latest version . I only play until they patch and start over.
