Hi, my name is ***** ***** welcome to JustAnswer!
I'll be honest and tell you that if the account is that old, and you haven't logged into it in a long while, it may be impossible to get back into the account.
Can you tell me when the last time was you accessed the account? Also, what service is the account through (Yahoo, Gmail, Hotmail, etc)?
Okay, and when was the last time you signed into the account?
