I am having the same problem. I've tried uninstalling and re-installing. I thought this fixed it, but the problem is back again. UGH! I can't do any of my work. Very frustrating.
p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.
