I tried earlier but couldn't get in, not sure how they got 5000 free tickets when nobody could get in. Kept hitting try again, also exited and when back in and kept hitting try again..again..
Tried getting in now and it won't work. It asks if I would like to try again, but the only option is to quit the app. Guess they don't want anyone else trying to get on now.
Edit: Finally got in, tried to order it, and like has been said all the free tickets are gone. If only this would have worked earlier. Oh well.
