old username or join date

I have an old username and obviously an old member date because of it. I have tried a few times to get that account active but have never had any luck.

The problem is the email associated with that username is dead and unrecoverable. is there a way that I can get my old join date associated with this username? or get the email changed on the old username and request a name change to this name?

any help would be appreciated.
