Crash with Avatars and Recent Global Posts Widget

Hello,

I am trying to install Recent Global Posts Widget. I am using BuddyPress and Network. This plugin requires Avatars plugin to be installed if I'd like to show avatars between blogs. But when I am installing Avatars plugin, I am getting following message - BuddyPress has already avatars function and Avatars plugin is deactivated..

Any ideas?

Thanks
