Yeah in the Curtains Down level my game freezes up and i get the error "Pure Virtual Call" or something like that. I'm using Vista 32bit, GeForce 8800 GTS, SB X-Fi XtremeGamer

I've tried all the updates/betas and nothing has worked...

FIXED:

Heres a quick how-to:
Customize the W2000 sniper rifle with the low velocity bullets. Begin the level and walk up the stairs and head to the left, when the guard passes, pick the lock and walk in, closing the door behind you. To your left will be Alvade, to your right, Delahunt. Press X to enter the sniper mode and snipe Alvade, Delehunt will act shocked and start to move, snipe him and drop the gun with 'G'. Exit the room and sprint (holding shift) to the exit. This should net you a completion with around 1:07 on the clock. You will get a Hitman status for this level if you do not get caught or kill ne one else. After you complete this level i've been told the error's stop coming because its some complication with the music.

Hope it helps.
