copied what might be the relevant portion of output_log here, but there were other errors further up in the log:

Saving game settings

(Side note: you might want to change the background color for [code][/code] tags in preview mode, it looks like it will be illegible, but posting the comment reveals otherwise. Very minor nitpick. )

Eh, I can't even browse that folder using an elevated explorer window. Tried resetting the permissions, got access is denied.

I think since it's a \tmp directory I'll try deleting it... if I can get the permissions, that is...

Hmm. Ran a chkdsk (had to schedule / restart to run it), and now the offending folders are no longer there, so I'm guessing filesystem corruption from when the power went out.

Just loaded the save successfully, so I'll mark this solved.
