Hi there - I delved into this a little more, and it looks like your domain meredithrom.com is actually isn't registered through WordPress.com. You'll need to log into your control panel at your registrarto make the DNS updates you need:
DOMAINREGI LLC

MyHostCenter
You can see the complete information here: http://who.is/whois/meredithrom.com
Just let us know if we can be of further help.
