Need old nickname to re register stand alone keys

[3rd.Rail]

Greetings, I have/know my two keys and the emails.  The nicknames (<= 5 total & <=3 per key) I have from older version licenses aren't correct according to the change name server.  I would rather not switch to the steam version.  Thanks in advance.

I took a read on how to register.  I found an old email that had all the correct info for one key. That key is good again in the server.  I will still need send for the remaining key as I still can't change the nick.
