I received nostalrius' account code and used it but none of my characters appeared in my control panel. On further attempts it says my code has already been used, which makes sense as I used it. But none of my characters show up, I have heard other people say when they used their code only a fraction or none of their characters transferred.
It may be possible that I used another username for the account and I recovered a blank alt account. I do remember the name of my characters on the account and their approximate levels, along with the email address used and the password. So if there would be account name recovery by email and password that would be great.
I heard some people saying delete your cache and cookies and try to get the code again, but that didn't work for me.
