Error adding event

I've just installed ltwCalendar on our server. I can log in and add a categories. However, when I try to add an event I get an error on the insert. Looking at the table, the insert is not including an ID (the first field is Name). I am using mySQL 5 as the database. Could this be part of the problem? All the other fields are correct. If I copy the query into phpMyAdmin and manually add a value for ID, then it will work correctly. Thanks for any help you can give.

OK, never mind. It was not the ID, but the recurring field, which was null and apparently mySQL 5 wants an integer.

I am also using mysql 5 and am having the exact same problem. I can add categories and recurring events but not a non-recurring event. What setting do I need to change, and where would I find that setting, to be able to post a non-recurring event? I installed ltw-calendar v4.1.3.

Thanks.
