Thanks Mark. I just reinstalled Premiere Pro CC 2014 a few days ago and used the Adobe Cleaner to resolve a different issue this week. (It worked.)
I had to start a project with a client’s laptop, which has CS6, then finish it at my home office, where I use CC 2014 (which I love). Granted, I’ll probably be in a jam if I have to edit it on that client’s laptop for some reason, but I don’t think that will happen.
Oddly, a different project that I did on that client’s laptop with CS6 opened fine (which actually will benefit from the features of CC 2014).
For what it’s worth, I worked around the problem by starting over with a new project to re-do the problematic one, using my PC with CC 2014.
