The email is only a confirmation of an email change, not the creation of an account.
I don't have the email when I made my account It's like 3-4 years old lol. I'm sure like 80% of the people who sell their accounts dont have the original email from nexon saying they registered, I looked around and saw some post with people confirming email changes and what not so I just thought it was good enough. This is my account, i can show you over join.me if you wish just message me on skype.
Online and taking offers aswell add me on skype its in OP.
