Hi @Leelee123, welcome to the forum and sorry that you've an old account on your BTID and this is causing some issues.
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 accounts linked.
Cheers
John
