mac calendar on maverick

My apple Calendar on just updated to Maverick is not functioning properly. When I add an event it won't let me type in it and when I try to delete it it says I must be an administrator to do so. Then when I uncheck US holidays calender the even disappears. And in this whole process somewhere I also get a menu saying data was lost in some kind of transfer regarding the Calendar. It's basically all screwed up and I'm not able to add any events.
