events calendar seemed to install fine; no errors. i upgraded wordpress before installing the plugin. now even though the events calendar seems to be running, i cannot add any events. when i create an event, and add it, it doesn't show up on the events calendar in the admin page, nor does it seem to show up in the widget on the blog page. i'm getting no errors and everything seems to be working besides this. i've even deactivated all my other plugins in an attempt to eliminate conflicts. there appear to be none. help?
