If setting Beyond Divinity to run on a single CPU was going to have any effect (I assume it didn't help), a new game would have to be started. The problem is either in the save files from the start of the game, or gets written in at some point later (ie with the first generated corrupt item).
With Ruskicowboy's save (before the arena guards) I did not get any corrupt items (other than the one already generated in the BF key chest) from the guards, ghosts or the spiders.
After jumping down the pit, I cleared the half dozen rooms to the north and west, and at some point the DK picked up some 'shoes darkbrown' which went into a ring slot. I didn't get much equipment in any of the chests, so I'm pretty sure they were dropped by one of the skeletons. I bought a few things after that from the imp in the kitchen, but none were corrupt.
I was going to play a bit more with this save, and do some other stuff, but have not had time.
BTW Lady Rain, I know you've mentioned more than enough RL stuff to keep yourself busy, but have you played BD at all under Vista?
