When I upgraded to version 2.2.0 the calender data was still displayed but it lost all the formatting. There was just a list of dates and events all in the same text colour and with the same background. I reverted the plugin by copying the plugin folder from a backup and everything was working correctly again.
Please let me know what information you require to investigate this further.
