thank you, I have been in touch with both Theymos and Cyrus.
The problem was identified, and some steps were taken to correct, but I'm now stuck. I require a moderator to 'activate' the original account.
'Activating' / unlocking a locked account can only be done by an admin, which is theymos, or cyrus (CMIIW). As long as you successfully prove that the account is yours (assuming you're talking about a locked account here), they will unlock it (let's hope so).
