i have a domain and i am using freehostia as a web hoster. In the name server of domain i have registered the name of both servers of freehostia. And in my control panel in the hosted domain section its showing "1 Hosted Domains / 1 Domains Listed".however on clicking on that its showing an error that "The selected domain name has not been registered yet. Please register it from the Domain Manager section first" now whenever i am trying to access my website by using dns1. its accessible but when i am using WWW. its not accessible

for example my domain name is example.com

if i will type dns1.example.com then my webpage will open but when i type www.example.com its showing "Oops! Google Chrome could not find www.example.com"

And for information 24 hours has been passed since i have registered my name servers.
