I image my machine regularly. Avid has responded, finally, asking if I trashed Prefs and did other things that I am, apparently, supposed to know to do instinctively, and without them adding a simple component to their Readme file stating "this upgrade may screw up your system setup and here's what you need to do to retrieve the functionaliity you had before the upgrade."
I'm about to try and figure out what they alluded to and see if I can get back to making music instead of computer repair!
