Domain Mapping Plugin not working need help.

So im working with a fresh install of WPMU and BP everything is finally fine and dandy so i wanted it take it a step further and install the domain mapping plugin.

I installed it and ran a test with no luck.

Put the NS1 and NS2 on the domain that points to my server did this and the IP's no luck.

It changes on the admin panel but its not working.

I must be missing something so this is what i did let me know if i forgot something.

its not allowing me to add a domain in the box designated for the domain name under the user admin panel. i type it in press the add button and nothing happens...

any ideas?
