Buddypress WPMU - Activity and Members pages are not showing.

I have installed buddypress on a wpmu setup. On the main site, buddypress works great.

I want to use buddypress on different sites, so I used

define('BP_ENABLE_MULTIBLOG', true );

in wp-config.

The additional sites that I add buddypress to, the activity page and the members profiles do not work. The groups, forums and blog network links work fine.

Does anyone know why this would not be working?

Thank you
