BackStory

The original goal was to add video upload capability to the WPMU/BP install. I found a video plugin, but it crashed this version of BP. I upgraded from 1.1.3 to 1.2.1 and the problems began. First, the link structure is messed up (and i have no idea how to correct this). Where wpmu.site.com/member/admin would take me to a page with my profile details (i believe its similar to the default profile/member page), it now just takes me to a content page with the same content as the index.

Problem

There are several hundred users/blogs on this site, and although i reverted back to BP 1.1.3 because i learned of the massive differences between the two versions, im unable to restore it to its original state. I do have a complete backup of the site prior to doing anything to it, however if i can figure out the link structure, and how to get back to the member profile pages i can just go from there.

Basically i need to know what all happend/changed when moving from 1.1.3 to 1.2.1 and then back, and how to get back to that.
