Domain Mapping Issue with Multi Site & Multi Blog Not Working


I have installed Wordpress Multi User, Domain Mapping, and the Multi Domains Plug in. I want to give users the ability to create their own blog. My site is at:

So far, users can signup and create an entry to create a blog. The target domain should be:

However, whenever a subdomain is created, the url does not work. So if I go to a subdomain i created, it shows up with a 404 error.

I updated the sunrise.php files and edited all the config files per the instructions. I also updated my A Records with my host.

Any ideas?
