Thanks for the feedback guys. I finally have my PC restored --minus a few items that weren't backed up. Not one to be deterred by disaster, I reinstalled CCleaner and turned it loose on the new setup... and it worked perfectly.
Don't know what happened the first time but judging from the overwhelming positive feedback for CCleaner on the site I figured it had to be a fluke. As much as I hated to reinstall everything (especially all the Windows updates) I think it was the quicker fix for me.
Any software site that has a helpful forum has got to have a good product line.
