Error message

I installed EventPrime to be used as a simple Vacation Calendar for our board members to inform each other of when they are taking a vacation.

I’m not sure what I did, but in the back end, I get a series of error messages that show at the top of every page or view that I am in inside WordPress:

EventPrime: It seems all the required pages are not configured.
For Event List use [em_events] shortcode
For Site & Location use [em_sites] shortcode
For Booking use [em_booking] shortcode
For User Profile use [em_profile] shortcode
For Performer List use [em_performers] shortcode

I don’t need all of these pages. I just need the one page that shows the calendar. I tried creating pages anyway and inserting the shortcodes, but the error message still shows.
I tried uninstalling and reinstalling the Plugin, but it remembered the settings and the error messages were still there.

Please help!!! Thanks!
