I have the same issue with logging on. The system told me that my log on name that I have been using for over a month won't work and it made me go through the whole new registration process. The problem is now I have lost all of discussions and threads that I had going. What is going on?
P.S. when i tried to call the help number the guy told me that adobe doesn't control the forums so they can' t help with the log on issue.
