Another Backup operation is running?

I recently upgraded from 360 to Norton security with backup.  It took some doing (trouble with support getting the product loaded on my system) but it seemed OK.  I ran back up once and then set up auto backup...which has never run.  Every time i try to start it i get the message "Another Backup operation is running. Please try again later".  I have rebooted several time and it is always the same for the last 40 DAYS?  When i try to run a manual backup I get an error in the status of my Backup DefaultSet...when I click to view details I get that same message.  I also get messages when I try to start Norton after a reboot that says it has install issues and it is doing general fixes.  That runs each time and is says it was successful but I always have this issue and that same issue fix runs every time I reboot.  Any Help???
