Installation: "Could not move file" during upgrade from 1.03b3 to 1.0RC1 on some images

If anyone has a chance to help, take a look at this thread. Sidtheduck helped me out there; maybe someone else can pick up where he left off. I have 117 images that could not be moved and renamed and reassociated with the DB during the Plogger upgrade process. I don't want to mess up or trash my Plogger gallery (which contains over 3,000 images) but need to get these images working soon, if possible. If anyone can help me do so, I'd love some advice or assistance. Thanks.
