my_calendar events not visible to users

I am trying to set up the plugin for my_calendar. Everythign looks good logged in as an admin user, but when I log in as any other user (regardless of role), the calendar shows up fine, but no events show in either hte list or calendar view.
If you go to add/edit a new event, the events previously entered are all there and I can add or edit new or existing ones, but they do not show up on hte calendar. If I log out and log back in as an admin user they all show up again.

Any ideas?
