Dell Data Safe Restore Question and Error Message –Softthinks Scheduler Fatal Error 0x1900001000000F

When trying to do a full system restore I get a message that says: “An error occurred during the selection of this System Backup.  Please check the source of this System Backup.”  Also, when doing a diagnosis scan using a program called ComboFix, a message came up that said: “Softthinks Scheduler Fatal Error 0x1900001000000F.”  So, maybe the two messages mean the same thing.  However, the restore and backup options for Files and Folders seem to be working.

Please advise.
