Question : Vista Backup error message 0x8007002

I am clicking on "backup", then on "Backup files for your entire computer"
I get the error message "The system cannot find the file specified (0x80070002)".
I kill this message twice, then the backup proceeds.
How do I get rid of this message?

I spent way too much time trying to fix this.  It's easier just to slap the installation disk into the HD and re-install windows.
