never had a problem with that quest, either. i wonder if the issue isn't sound related (which was my case). another workaround for that particular problem for me was to turn off the sound before starting the game. once the game was started and i got past that particular point, i saved my game, exited the game, and re-enabled the sound.
it was a very lengthy process for sure (especially since it was just an area transition for me), but it might help you get past that particular section.
