Unable to log in

I registered a new email address with Avast! as my old one is no longer valid and registration due to expire. So I logged out of that account, via the Avast! “Account” option, but it won’t let me log in to the new account. When I click Account then Log In all it does is say “Retrieving Information” for a few seconds. There’s no indication as to what has or has not happened. I’ve found older threads related to this issue but I can’t find a solution posted anywhere, so I thought I’d resurrect this Avast! BUG!

Please sort this out, Avast!.

Avast! 8.0.1489, Windows Vista SP2
