I installed the Jacquie Lawson Advent calendar on my MacBook for the 3rd year. Never had a problem before. It ran ok for the first 5 days and then just stopped. When I try to open it all I get is a menu at the top of the screen that only allows me to quit. All the settings needed were fine. I uninstalled and reinstalled a couple of times, uninstalled and reinstalled Adobe Air...still no go...
