Single Group Event does not work!

I installed your plugin for Buddy Press Group Calendar. It does NOT work. I used the Single Group Event widget so that I could have a calendar for the entire site on the Home Page. However there is no way to add an event!!! The Group Event Calendar works...but ONLY in groups. I want a calendar for the entire site, not just a group. I read your instructions, watched the video, reviewed forums, looked at every option in my WP Admin...yet I have found NO way to enter an event. I attached a shot of my Home Page. Notice the widget on the right hand side is there, but there is NO way to enter an event! Any suggestions???
