Voila une reponse que j´ais trouver sur le site officiel de Bioware kkun peut m´expliquer svp ? ??
I think I may have just solved this issue.
I went into the Motherboard BIOS and lowered the AGP setting from 4x to 1X/2X. After doing this I can get into all the areas I couldn´t previously.
This sounded strange so I changed the setting back and retried it. The game froze again at 3/4 of the way.
Changing back once again to 1X/2X and the game and areas load fine.
This is really strange. It says right on the box my card came in (GeForce2 MX) that it supports 4X fast writes. Oh well, at least I´m playing again.
I hope this helps you and some of the others I´ve seen with this problem.
