Pardon me if i am a bit late to the trread ,but i faced teh same issu and i think its because of some issue with QC , i tried to uninstall it and found out an easy way by deleting my profile with another admins login and again logging back and opening QC one more time.
the QC takes its own sweet time to load for teh first time and "Class not registered" error is no more found.
