Hi, onceblindstudios. That is a bit of a bind.
I’m afraid that until you can check for conflicts, it will be difficult for us to help you troubleshoot.
Until you can do some testing, your best bet is probably to try downgrading to 3.1 and see if that gets you back in business:
Restore your plugin to whatever version you had previously by deactivating The Events Calendar plugin and add-ons and installing your previous version. You can get previous versions of The Events Calendar here: http://bit.ly/13LO7ji. Please download the premium add-ons you need from your account’s download page: https://theeventscalendar.com/downloads/
