question from an idiot re: neteller/empire and losing my account email

[Adam22]

ok here's my predicament:

i signed up for empire a few months ago, played and cleared the sign up bonus, then went back to my usual sight, leaving the money in that account. now i want to play on empire again but i cant remember the account name or the email i used to make it. i checked all my normal emails i use with empire and they said that no real money accounts have been made using those accounts. so basically i must have made the deposit using an email that i have since forgot about, so i am stuck trying to figure out what my username/pw are without the email.

so what i'm asking is: is there a way to figure out what my username is without knowing the email via the neteller transaction history? what would you do in this situation?

please forgive me for being so stupid as to have forgotten my username.

thanks
