I believe that running the "issues" portion of Ccleaner may have done something to a program that I had not used in awhile. Yesterday when I attempted to launch NTI Backup Now 4 and NTI DriveBackup 4, I got the Stop 0x0000000A error in Windows XP and it brough the computer down. This was tested on two different computers I have, causing the same thing on both. I called NTI and they said they have seen this before with registry cleaners. I reinstalled the programs and now they are working fine, but I am wary to use Ccleaner to fix "issues" again.
