Game freezes at end of load screen as I enter Underground Sea area

[John Mullins]

My game freezes at end of load screen as I enter Underground Sea area. No errors, it just exits out. At no point do I see Underground Sea area. I have been to this area earlier in the game with no problems (but that was on a different computer?).

I have just come from Mehgard and am on the quest to find the Portal key in Demonis. Problem is, in order to get to Demonis I have to go through the Underground Sea. Now I have a level 26 character and cannot continue the main questline.

I have tried copying this save to my friend's computer and running the game. Same problem happens.

This save game file has been moved from computer to computer with no problems until now. Because it has been on different computers with completely different specs (from OS to video card manufacturer to processor manufacturer), I don't think this is a component problem.

Can anyone tell me a solution to this problem?
