Multi-DB is not able to create new sites

Hi, I am just about done wrapping up an install before I start selling service. I installed Multi-DB and configured 20 vip sites and they all work as expected. Immediately following I tried to create a new site and it gave me a 404 error after adding the site. The new site redirects to my main domain and I can't login to it?

My domain is and I have enabled access to your support team for debugging.

Please let me know as soon as you can.

Thank you,
