I keep getting weird errors when using SSE2, along the lines of (not verbatim!):

"Unknown internal error!"
"Can't find source file."

I did manage to get the scene to render twice, though.

I'm using the non-SSE2 executable now, and it seems to be working without
problems. At least, it worked the first and only time, and hasn't stopped
rendering yet.
