i switched my email as i no longer use the old one

If you have already registered the serial in Native Access using another account that you have no longer access to then you will have to ask Account Support Check this article "I Have No Access to My User Account"

All issues regarding account and registration are handled exclusively by N.I.Account Support , they can also help you merge two accounts. Also if you had account access then you could transfer transferable serials yourself when more than six months ago that serials were added to account , in that case treat it as if you would sell to another person. : Quote Matt_NI : All you need to know about License Transfer

In case that you need guidance contacting support : Please read : how to get support !
