I've been trying to beat this error and can't get past. I'm trying to play through the story mode, and I'm in Chapter 8. In the CGI cutscene where Lou uses her SUV attack, at the same point, the scene freezes and an error message pops up that psuoff.exe has encountered a problem and needs to close. I'm running a Gateway laptop:

Intel Centrino 2G Core 2 duo, 1G ram, Win XP Ver 2002, all updates and patches, Intel 945GM video adapter, integrated audio. I've uninstalled the anti-virus software (after running to make sure no viruses), removed all processes except this and explorer, tried reinstalling PSU and changed the video and sound settings to the minimums in PSU, updated video and audio drivers.

Any help would be most appreciated. Thank you!
