I installed Events Calendar 2.0 fine by uploading a zip file from the wordpress admin section (via the plugins upload area). Acitaved it and then started using it and it worked just fine.
Then I purchased Events Calendar Pro and tried to install it the exact same way and I received an error:
Fatal error: Call to undefined function get_current_screen() in /home/content/s/l/o/slowfoodhunt/html/wp-content/plugins/events-calendar-pro/vendor/advanced-post-manager/tribe-apm.php on line 180
I can still at this point navigate through the website, but no longe the admin area until I manually delete the plugin from server via FTP.
I made a short screencast of my troubles here:

Any assistance would be greatly appreciated.
