I'm re-dling the client as we speak, turns out there's another person from my other server on here so its like...Awesome =D Anyway, lets see if I remember my user info x_x. I have an idea as to what the pass is =P
If you remember your account name, you can send in a support ticket (click on my signature) to retrieve the password. The GMs in charge of handling the passwords will contact you about it.
If you cannot wait (or prefer to do this instead), you can also start a new character and I'm sure all of heRO will welcome you warmly in the same manner ^_^
