I've checked your account in our database and it does look like the account has been removed. If you have not logged in within 18 months, the account is considered inactive and may automatically be emptied by the server. We went through not too long ago to remove any accounts on the forum (and in-game) that were not active, so if you have not logged in for quite a while, we have, unfortunately, likely deleted it. We're working on getting the Registration back open so that users can create new accounts, so hopefully you won't have to wait too long before you can create a new one, if you so desire.
I will go ahead and lock this up, seeing as the issue has been discovered. If you have any further questions or concerns about the account or anything else, feel free to PM me or another staff member, and we would be happy to help you.
