Molten-WoW account recovery.

Is it possible to receive any credits made for donations during the Molten-WoW era or even regain an account? I had an account thriving back in the day with molten with a lot of money donated towards the game for in-game items. I looked at my old emails from 2010-2011 and I found the username I had with Molten-Wow and used it to create an account but it said the name was already registered. So when I went to reset the password it couldn't successfully send me a password reset even though I submitted the correct information.
