I solved it by deleting the theme in the folder where they are stored!
Yikes - hard to find...My Computer\Shared Documents\Stardock\Theme Manager or C:\Docs and Settings\All Users\Documents\Stardock....
You could be right but I use same Icon Package all the time and other suites don't mind being deleted!

Think I'll store them on my Data partition in case of crash...(which I've never had)...
