Ok I think I know what your problem is

You need to change the windows mode that it runs in. You need to go to the folder where your maintenance program is installed. Right click on the Maintenance program and click run as administrator. Now in the window that comes up, you should see where it shows which windows it is running under. Switch the mode to
"XP service pack 2 mode", then click ok. This should fix your problem and it should work after that. The reason it does not work in vista mode, is that it was built before vista was. Let me know if this works. BobbieLee
