Ok, so after a month or so without being able to login, with application manager crashing, etc etc, I now have the new Creative Cloud application installed. And I still cannot login or update my applications.
Message for the past 24+ hours says "Unknown Server Error: Sign in is currently unavailable. We are unable to access your account. Please try again later."
This is now over a month of this lack of service without a word of apology or explanation from Adobe.
