Here is my problem:

I enter Stormfist Castle through the sewer, get the script first with the message that I have been trapped and find myself in a room shielded of with some sort of energy barrier. Now, when I walk around a bit, a new script starts with Zandalor and one of the divine ones (who gets killed in this script). The scripts then freezes with Zandalor in view (after he says "damn, I am trapped" or something like that). After waiting 10 minutes I get a message saying that the script has not ended for 10 minutes and that there is a problem. Tried this numberous of times, but the game never continuous.

I started my character with the retail version and updated afterwards to 1.34, I have been playing for quite some time now and really would not like to start over. Is there any known workaround for this problem?

System specs:
Celeron 1.4Ghz (Tualatin) with 512MB
Geforce 4 Ti4200
Win XP

Character created with v 1.0029
Divine Divinity afterwards patched with v 1.0034a (the latest)
