I just wondered if anyone might have an idea why I'm getting a CTD when I start the game. It's a Steam install, and I literally was playing yesterday with no issues. I un-installed then re-installed and now I get about 3 seconds of the Bethesda brand video and then it drops. I have this from my event viewer.

Faulting application name: Oblivion.exe, version: 1.2.0.416, time stamp: 0x462392c7
Faulting module name: Oblivion.exe, version: 1.2.0.416, time stamp: 0x462392c7

Faulting application start time: 0x01cc1d43475e5a90
Faulting application path: c:\program files (x86)\steam\steamapps\common\oblivion\Oblivion.exe

Again, this was working fine yesterday. Any assistance would be greatly appreciated.
