This is the relevant OBSE log:

Seems to be registering okay. I tried running the game with all OBSE plugins removed, but that didn't help. I'm on W7, so I have .NET Framework preinstalled. What could be the problem?
I've tried countless times, and only encountered the error posted above the one time. Other than that, when I load Oblivion, all I get is a freeze, and the mouse cursor appears and I can move it around. But when I click the mouse, I get the Windows error sound (I think it's the error sound - One of those Windows sounds).
