Tried adding BuddyPress and got a fatal error

Hi,

I have Edublogs home page (parent & child) installed on a multisite. I at first didn't think I wanted Buddypress but then decided I did.

I installed buddypress, network activated it and began stepping through the steps to set up buddypress. I got to the last step and then got a fatal error. I deleted buddypress and was able to find the site again and everything looked fine.

My question is: if I'm going to install Buddypress do I have to change the theme? Or do I have to deactivated the theme on all my sites (main and subdomains).

I think I want to run the bbPress Edublogs theme.

Anyone who's been though this I'd appreciate your help!

Thanks!
