Do you have more than 1 BT account?
Hi @Tim1729, welcome to the forum and thanks for posting.
What @imjolly is asking is if you've more than one account linked to your BTID? If you've used the same email address for your new account as the previous account then that will be causing this issue.
If you have used the same email address then if you are able to set up another BTID with an email address that has not been used as a BTID before and it will work ok.
If you don't have another email address you can use I've sent you a Private Message so you can get in touch with the Mod team and we'll probably have to delete the BTID so you can set it up again without the old account linked.
