You could always try to uninstall with CCleaner, but it uses the native app uinstaller.

If you saved the program when you downloaded it, I would suggest running the installation again, and then trying to uninstall after a reboot.

If that doesn't work, email support@stardock.com . Keep the auto-reply and don't write to them until you get an email from an actual person or you'll get put to the end of the queue. You probably won't hear from support until Tuesday or Wednesday... weekend plus holiday.
