Hi there,

Do you remember the Microsoft account or email) it is tied to and the password of that account?

Didn't think I did but guess I have to run through the various mails - tyvm for the answer

It sounds like you used a different email address for the old GT. The system won't allow you to create a new tag if the email address is already in use by another tag. Are you sure you didn't use a different email address and password for the old tag? They
have to match exactly for you to be able to log into your account.
