Yes. The only extensions that appear to be live in my PS 2014 are Floating Adj and the latest Kuler. (I can always access the others by re-opening the photos in CC, but what a nuisance!
I re-installed the Waterclour Assistant ext. that I had removed as a test. I used the additional download instructions on the add-on's page. Still no joy, though. Don't know what else to try, and I don't have time to do a chat or phone call now. Maybe later.
