 * I just tried to update the calendar as it was telling me there was a critical
   update. It completed broke and disabled my ability to get into the backend so
   I deleted the plugin completely via FTP and tried to Add New Plugin through the
   backend once I was able to get back in. When I tried to do that it said unable
   to add plugin, invalid header file.

 * I’ve got the same issue. Exact words: “The plugin does not have a valid header.”
