On my Windows XP SR2 system, RegSupreme Pro worked fine for several weeks. I didn't use it for a couple of weeks and then when I tried to scan the registry in "normal" mode before cleaning it, after part of the scan the computer spontaneously rebooted. I tried it in safe mode and for an instant before it rebooted I saw an error message that had the word "paging" in it. I don't think the program is the cause, but do you have any ideas for me? Thanks!
