Hi @James212
Welcome and thanks for your post! I have moved your post to create your own thread discussion.
I am sorry for the problems you're having with the older account on your BTID. Give one of our guides in the helpdesk a shout on 0330 1234 150 and they'll be able to help you with this.
Feel free to post back and let me know how you get on chatting with them.
Thanks,
Robbie
