3.2.1 Broke MainStage

Do no update! If you already have and Mainstage will not open for you, you can hold down option and click the mainstage icon (keep holding option). It should open the main window for you instead of the last concert. At that point, it won’t open any concert for me (including the default ones). Your results may vary but I hope this helps you.
