Domain Mapping- 404

So I had my Wordpress blog at megamers.tbreak.com

I setup WPMU at tbreak.me and imported the blog into MU.

At my registrar, I tried both CNAME and A for megamers.tbreak.com pointed to the IP or megamers.tbreak.me but when try to access megamers.tbreak.me, it goes to megamers.tbreak.com and gives a 404 error:

Not Found

The requested URL was not found on this server.
