Stuck in Requiem Level 6

[eoverton]

I'm having a similar problem to the one mentioned in this thread:

Specifically, the framerate drops to about 2fps when I load Requiem level 6 from the menu. All of my saved games are in level 6, so I can't even try playing through in one go from the 5th level like the previous poster did. Anyone have any solutions? Or barring that, could someone point me to a save file from the next level? It'd be a shame to have to stop playing the final game because of a glitch.
