Kept getting this when I tried to login.
You could not log in because the service account in question is not registered.
If you would like to log in to the service, please log in to the Square Enix Account Management System and register the service account.
Any ideas why?
Not sure if you got this answered, but to fix that make sure you are logging into your SE member account that has the same email that matches the one that got sent the beta invite.
I got the same error then realized that I was using the wrong SE member sign-in :3.
