maybe the support server is also under maintenance...
Edit: i used the serial found in my email, it doesnt say "under maintenance" anymore,
now it just says "licence...not valid".
very frustrating
Edit 2: while trying offline registration i get:
General activation failure.
Details: The input is not a valid Base-64 string as it contains a non-base 64 character, more than two padding characters, or an illegal character among the padding characters.
Edit 3: back to the ''under maintenance" error.
