Buddypress Activity Plus "re-install" problem

This plugin was working for me but after the following actions is not working for me.

I was having issues updating plugins that I had uploaded via SFTP. So all plugins that I originally installed via SFTP I also deleted via SFTP. I then reinstalled each plugin through the "in system" method. This one was re-installed through the WPMU plugin system. It doesn't work when i network activate it or activate it on single site.

Any ideas how to fix? Thanks!
