when running CCleaner 2 beta build 475, it initially worked OK, but has now started to display the (image attached below) error while halfway thru the cleaning cycle. it does this when run at startup or when run manually. reinstallation on it's own does not help. reinstalling the old 1.x then reinstalling 2 beta does work for a couple of days (and thru a few reboot cycles) before the error happens again.
system is a p4e-3ghz, 1.5 gb ram, via chipset, 2 sata drives, ati 9700 pro video card, windows xp pro wi. all updates.
