transfer domain name to homestead

I have my domain name registered with Melbourne IT, but my website is on Homestead (www.gnmrc.net). The domain name recently expired, so I want to trnasfer the domain name to Homestead. I followed the instructioins on the Intuit community help section, but when I enter my domain name and click "use this domain" I get an error message stating a website is already associated with this name. Is there a link to instructions for transferring my domain name from Melboiurne to Homestead ?
