Norton 360 V3 hangs while trying to magange backup sets

When I try to manage backup sets the backup manager dialog will say it's getting information and the little circle pacifier will come on and stay on forever. 

 

I won't stop and let me pick a drive to back up to or selecet the files I want to back up.

 

Any body know how to fix this one.
