update please

I played the first bioshock game and loved it. So when I saw bioshock 2 I got it in a heartbeat and loved what I saw, until level 2. The game crashes on the the loading screen between levels 2 and three. Also some of the graphics look glossed over without alot of texture, especially on teh big daddys. Please Update.
