Made an account to post this! I know how opaque this reload code business can be.
I got the All In One Calendar working by putting the following into the reload code box for the Ajax Loader:
jQuery.getScript( '/wp-content/plugins/all-in-one-event-calendar/app/view/admin/js/pages/common_frontend.js' );
jQuery.getScript( '/wp-content/plugins/all-in-one-event-calendar/app/view/admin/js/pages/calendar.js' );
jQuery.getScript( '/wp-content/plugins/all-in-one-event-calendar/app/view/admin/js/pages/event.js' );
As Courtney suggested, but this is a copy/paste job now hopefully for anyone else messing with it.
