Cannot unregister a different user from my console

I have been accepted for the preview programe and have been sent the message with the launch for the app. Unfortunately my older brother has used his account with preview programe on my console when he visited and now it will not let me register my console. I have been on his account and used the manage devices on the preview app but it is not showing my console. It only show his own console. Any ideas what to do ?
