I've tried a few of the "fixes" that I've found in a few different forums, but nothing seems to work. (Audio and video fixes on crashing checked)

I keep getting a visual c++ runtime error of (R6025 pure virual function call) I checked it and its an issue with the scripting.

I wanted to see if anyone else has been having this problem since the 1.1.1 patch, and if they've managed to find a fix for it.

It only happens during the ending cinematic and generally crashes with the aforementioned error or just a hard crash back to windows and a general "Windows has encountered an error and will now shut down this program." message.

So any help here would be great, since I'd really like to see the ending that I spent 130+ hrs of game play time to get.

Windows Vista x64
