kbateson - Please make sure you have the latest video and sound drivers for your PC first. If you still have issues, then zip up the following files and email them to [email protected] with a description of your problem.
+ Dxdiag report (click Start -> Run -> type "dxdiag" and hit enter -> Save all information)
