As has been said many times now, if you don't have access to the email address you used:

* If you have a device that can still log into that account, change the email in game (nexus -> my account -> modify account)
* Otherwise you'll have to contact support and prove that the account has always been yours to get them to change it to an email address you do have access to.

Closing thread, since we're just getting variations of things answered by this over and over.
