Crash in Jerro Haven....HELP!! Don't think there are any spoilers here

[MoonbiterStolen]

I have played the NWN2 Original Campaign for quite a while and it gets to Jerro's Haven..... but it crashes when the place has finished - as soon as he waves his arms about and teleports you out of there, it loads the new areas etc, but when it would be about to bring up the actual game screen (at the end of loading), it crashes. Every time.

I've even redone the whole level from a save just inside the haven. I was going to go back to an earlier one, but I don't think it's worth it unless this is fixable at all...? Help? Lots? Please?
