WordpressMU not displaying site, but Buddypress works fine. Any ideas?

Hi gang, I'm a recent new member and have a basic question. I've done the WordpressMU install and had no problems, then installed Buddypress and installed the Corporate theme (nice!) But the problem is that the main site simply doesn't render at all (no errors, just a blank page) after all is installed. No plug-ins are present other than Buddypress. There are no problems logging into the dashboard or seeing my Profile in Buddypress.

The site is http://hoopsjones.com
My public profile is here: http://hoopsjones.com/members/admin/profile/public/

It's hosted on GoDaddy with a dedicated IP on a Linux server. IP address of server is 72.167.232.110

Any and all help is appreciated.
Cheers,
Scott
