WordpressMU/Buddypress Registration Fix

I have a Wordpress MU + Buddypress site I had a little work done on (3 extra fields added during blog registration). For some reason, when we register a new blog, the blog isn't linked to the newly registered user's account. Under Site Admin > Blogs, the blogs don't have a user listed. It also doesn't show up in the blog directory until I go in and manually add some missing fields. I notice that there's a few tables (such as wp_registration_log and wp_bb_user_blog, wp_usermeta, etc.) that aren't getting all of the information. The db is also flagged to not be public, even though we check the box to be public. I need someone that is experienced with WPMU AND Buddypress to make sure the registration process is working 100%. Please be sure to include an accurate turnaround time as this is an active project of mine.
