For the past few weeks, we have been sporadically unable to add a new event to the Event Calendar. This is occurring on all our computers, including the one on which the PowerChurch data is stored. When I click "Add a New Event", it lets me go through the whole process of inputting the event information, and when I click Finish, it says "The event has been successfully added", but when I close the window, no event has actually been added to the calendar. This only happens some of the time, though--if I come back an hour later and try it again, it might work.
Only once have I gotten an error message of any kind: http://i.imgur.com/U8qiCzO.png
