Someone needs to confirm this, but I believe that the conversion from RC1 to RC2 eliminate some activity stream tables.
Parts of this thread my answer your question, Jfcarter.
Thanks, Jeff. Is there a way for me to restore the information?
You have to visit the back end of wpmu as site admin to upgrade your tables to RC2. What it does is in sequence:
1) Create a new site wide user activity table
2) Move all the individual user activity table entries into the new site wide activity table
3) Remove all the individual user activity tables
4) Set a flag that this has been done in site options (meta) called ‘bp-activity-db-merge’
bp-activity.php – bp_activity_install() Jeff.
Did you visit the wpmu back end as site admin?

Thanks for this information. I haven’t yet upgraded my tables to RC2 and don’t really know what to do. The rest of the install is complete and working fine.
Any tips or pointers you could give me would be appreciated.
You don’t have to do anything except visit the back end admin area of wpmu logged in as site admin.
Not to be dense, but I’ve been to the backend of the site already logged in as admin–is there someplace specific to go?
Maybe it’s so obvious I don’t see it.
Not admin, site admin and nothing spectacular happens overtly. When you look at your tables with phpmyadmin do you see lots of tables of the format wp_user_xx_activity? One for each user on your site where ‘xx’ is their user id.
bp-activity.php – bp_activity_install() Jeff.
Thanks, Burt. I knew it was in there and that some activity table merging occurred in RC2, I just could not remember off the top of my head and I was dog tired to go look. I went to bed about 2 minutes after posting.
I kinda figured that was the case. Sleeping at the kb and all. 
I wonder if people are actually running 2.7.1? I hit Site Admin > Upgrade and I\’m still on 2.7.1-beta1 but it happily goes thru and say success, done! It\’s not doing anything.
The other problem is that 99% of bp users don’t have a test/dev site so any problems encountered are on a ‘live’ site.
@Burtadsit
Yes, I do see all of those tables. What does that mean?
I think I am having a similar problem. I checked phpMyAdmin and it looks like the table conversion was completed.
Not sure what to do with this.
