Hi,
I see that you've purchased the domain mapping for lovetransmission.com (which is different than registering the domain through us), so if you own that domain, you'll need to log into your domain registrar and update the nameservers to:
- ns1.wordpress.com
- ns2.wordpress.com
- ns3.wordpress.com
You can see more details about mapping an existing domain on this support page:
http://en.support.wordpress.com/domains/map-existing-domain/
If you aren't the owner of that domain, you can go to your dashboard, then cancel and refund the domain mapping by going to Store -> My Upgrades, then clicking "Cancel and Refund".
