Thank you, @proxos666 ... I am so bummed about this. I DID have a different email to my SWTOR and EA account once upon a time, both the same email, which I have since changed.
I still have 100% access to that old email, and I've been trying to find ways to... figure out if that's the email SWTOR wants, but I'm not really sure how. My account has been updated to a new email, and I'm not sure how to tell it to communicate with the old email. I am hoping to call EA CS tomorrow if possible, and I did send an e-mail to the support team.
Hopefully we will be able to resolve this soon. I appreciate the flag for support.
