Well, I have had quite a few problems with Neverwinter Nights - crashes, disappearing items, having to start the game a few times just to play the Official Campaign. How do I play my character in Chapter 2 if I restart the Official Campaign? If I am starting over, won't I lose my game? And how do I insert the code messaged above? Starting over is a real kill for the game '>
Yah,with so many problem you prolly get many more. Something corrupt. Also, maybe bad vdriver match cause area load problems. Could be both bad install + wrong driver together. Repatch is best idea. Make sure no hak or override in rebuild so move all CC stuff to temp folder til get OC running right then move back... if you install any CC stuff before trying OC.
If you do all this and still have crashing and burps like you say, then time to repost to Tech Support since spoilers can't fix it. Then you need to give all machine stat like OS, vcard/driver, ActiveX version, etc. since it could be many things. But wait til you rebuild and try new game or load save.
