Fatal Error with Appointments Plugin

Hello, I recently updated Appointments+ however I am getting this error:

Fatal error: Call to undefined method Google_Client::setLogger() in /nfs/c07/h01/mnt/102891/domains/kocachiropractic.com/html/wp-content/plugins/appointments/inclu?es/gcal/class-app-gcal-api-manager.php on line 58

I renamed the folder so that the site was not broken.

Can you please advise.
