Ah ok, i thought indeed that you needed to recover your ingame account. Then you need to wait for someone from the management to help you.
Anyway yes, one of the e-mails related to those accounts has the "dorin" part in it.
Another one has a different e-mail, starting with "alex". If you wanna try to use it but you can't remember the complete e-mail let me know, i'll send you it in pm
