When I try to map a domain I get an error message:
Someone (maybe you?) already registered blog.liveinsite.com, if you own this domain you can map it to your site now.
When I use the Domain Helper, http://en.support.wordpress.com/domain-helper/, tool it says the domain is available.
What can I do. I gather I need help from Support but there doesn't seem to be direct access to them.
