I'm having problems in Dark Messiah: Might and Magic. After I complete the Prologue and finish the cutscene, it loads up to Chapter 1: Gates of Stonehelm. At the beginning, everything is usually fine, but when the gates get attacked it starts acting up. As I am being dragged trough the door, the screen switches to an image of an earlier part of the Prologue (its usually random) and switches back when I'm standing up. When I try to move it gets very choppy and I can't move without appearing in front of a wall. Also, when I go to the Load game screen the the games photo for the Autosave is full of colored squares. I don't know if it has anything to do with it that I purchased it off of Steam. I have tried uninstalling and reinstalling it about two times. I have no idea what to do. If anyone is able to help please reply to me with an email or with a reply.
