the whois details for your domain is registered properly in your name, so there isnt an issue there, and the name servers have been changed to point to the new servers (new website) so it shouldnt really be any problem.
Was it you that changed the nameservers when the new site was built or was it your old host that changed that for you?
If it was your host, it should be easy enough to get them to change the tag, that way the domain can be moved into an account that you have control over.
Bryon will know alot more about this is as he deals with domains on a dayly basis.
It should be pretty easy to sort out
