There was simply no admin menu items for the plugin. I have seen this issue with other BuddyPress Group based plugins, specifically bp-group-management. For that plugin I ended up going to the URL for the admin page directly.
The issue appears to be related to having BuddyPress installed with multiblog enabled and a work around for Group Forums. Here is how I installed BuddyPress to get Groups Forums working correctly with BuddyPress MultiNetwork (Brajesh Singh version)
At the network level;
1- Did not enable multiblog
2- Install and activate BuddyPress plugin and setup the Groups Forums.
3- Enable multiblog
5- Installed and activated BP Multi Network (Brajesh Singh version) This moves the Buddy Press Admin menu to the site level which is where the Group plugs are failing
6- Recreate the BuddyPress pages
