If you link some of the Zeni peeps in your post, you might get help a lot faster, normally on these kind of threads they are fast about it.
Not sure who in particular deals with this stuff, but try linking @ZOS_GinaBruno or something, as I just did.
She will point ya in the right direction I imagine:}
Also, you normally get a login code sent to your email that is linked with your account, I know you switched emails, but try a forgotten password with your original email or something.
Takes 5 seconds to do, saves some leg work on both ends of the fence too.
Good luck.
