Multi-domains plugin and membership site conflict?

I installed the multidomains plugin and the membership plugin on the multisite network. I created a wildcard subdomain for the site [Edit: Link removed at user request] (/public_html/74.53.88.50)

When I go to [Edit: Link removed at user request] it takes me to this URL and it says I can't register. This is because I turned off registration in the membership plugin as was instructed to use the membership plugin. What is going on?
