If you can't remember the e-mail attached to your account, you need to send in a ticket via this; Recover A Lost Account.
Try to include as much as this information as possible~
1) Your full name
2) The email attached to the account
3) An alternate email we may attach to the account (please make sure you have access to this email and it is NOT currently attached to any Aeria account)
4) Your IP address (WAN IP ADDRESS)
5) The Last time you logged onto the account
6) Character information (names of all the characters on the account along with the gear and levels)
7) Where you live
8) Any AP transactions you made with the account
9) The name of the account in question
10) What does the account name mean/ stand for?
11) Country of origin this account was created in.
If you can provide enough information to prove the account is yours, they will help you recover it. I also suggest taking out the personal information in your post, as it can be misused by other people. Good luck with your issue.
