OK, I just checked, and looks as though the registration is not complete yet.
So I've got the following suggestion to make. Go into your domain account and change the name servers to ours. At the same time go into your cpanel and park your new domain there. It may take a few hours, a day or more for the DNS settings to propagate. In the meanwhile you'll still have use of your cPanel.
Once your new domain is sorted out, we can change your name very easily. Or you may wish to retain your old name as when you do, even if your domain should for some reason go down, you'll always have access to your Website.
