Multisite Pro Sites Upgrade Addon sites isssue

Hi Guys,
I am back again and here is what is up. After the last very long postings that helped me cure my issues with prosites/domain mapping ect I have been doing the polish on my site and testing further. I have discovered tonight I have a new unique problem.

When ever someone has a site and if they want to create a new one that is just plain it is not happening. They can click the registration page but it only takes them to upgrade no option to create a new site. if they click their account link in their admin menu it just redirects to the upgrade page even with a 1st level pro site.

Maybe you can give me a suggestion to point in the right direction thanks.
site is http://TheFitYou.ca
