I have tried CCleaner one time and liked it---except that it deleted a paid-for downloaded program (Bookworm Deluxe) and I had to re-download that program. I was told that I only have a couple of these "re-downloads" available and then I will be charged for doing so. My question is-----how can I run CCleaner and not have it delete my Bookworm Deluxe program? Thank You.
