I am encountering a glitch at the very beginning of chapter 1 rendering this game unplayable. This glitch is occuring when you learn how to shimmy. As I am shimmying across the dome building Anakin jumps over the ledge and through the roof and I die. I am currently running the retail release of Windows 7 Ultimate with a ATI Radeon X1650 Pro. I have the current drivers for Win 7. Any ideas of what's causing this and how I could fix it?
