Domian Mapping Not Working

I have installed Domain Mapping on a subdomain network.
Dedicated IP.
Configured it.
Moved Sunrise.php to the Content Directory
Modified the WP Config File (typed in details)

Pointed a A Record of a domain to my IP the pointed domain "REDIRECTS" but works like when you "FORWARD" a domain. The Mapped domain name once gets to the site the url becomes the main site url, not the mapped domain.

It also seems to point at the master domain not the subdomain for the account setup and mapped to.

Also when I go to Tools>Domain Mapping> and I input the doamin and hit "ADD" the domain I input dissappears.

Can anyone help me with this?
