Here is an example on how to update events:
|EventsManager manager = new EventsManager("Events");
|IContent cnt = manager.Content.GetStagedContent(new Guid("441b6bbf-79b5-463f-926d-4ba48f634d1a"));
|cnt.Content = "Test edit an event!";
If the above does not help, please post your code to investigate it locally.
