Changed Password For Account, lost access:

[NEED_HELP]

Hi, guys... I'm a very long time player.. I've got another account, (separate from this one, as I've now lost access.....) that I have just changed the password on... I started this account back in 2010, so I don't have a clue as to what the email was I used to register this account under or even how to access it...

I changed my password for my primary account this morning... about 10 minutes ago, and I KNOW what I typed into the change password field both times... but now it's not letting me log in... I've tried just about every combination of spellings... checked if I had caps lock on in different combinations... I'm at a complete loss... I can provide what I think the account password spelling is as well as the original OLD password... I just am completely locked out and I'm devastated...

I really hope someone on here can help me... I can provide any and all details of every character on every server.. everything, please hope to get some help here. I don't know where else to turn.
