I ran fixccs.exe from D:\ and D:\WINDOWS\system32 (on my machine, which runs WinXP Pro x64 SP2) the system drive is D: . This system has been working reasonably well (only the usual minor glitches one expects from Windows, which I have been able to resolve until now) since early 2005. Now I can't see devices in the Device Mangers, I can't run Windows Backup and sigverif.exe returns a "The data is invalid" error message. Any ideas?
