Pagination Broken and Fatal error: Call to undefined method…

First problem: When I click on “Test Connection” in the “Google Calendar API Settings – BETA” I receive this message:

Fatal error: Call to undefined method Google_Client::setUseObjects() in /home/nonageor/public_html/client/tgf/wp-content/plugins/appointments/includes/class.gcal.php on line 958

Second problem: The pagination is not working.

This is a theme conflict as I tried another theme temporarily and it worked great. Any suggestions as to what I can do to fix it?
