So I played the Halo 3 Flight on steam for a while when it first came out, but then I stopped playing for a couple weeks. I had no problems with the flight during this time. When I recently went to get back on the flight, it updated itself, and when I tried to play it, it was simply a PNG of the Halo MCC logo and did not let me enter the game. I tried uninstalling and reinstalling multiple times, and it turns out that the application is now only 2 mb. I have not received any notifications that my flight has been cancelled, and my code still works. Is there anything that I can do to fix this?
