I dont understand why, but everytime I set up a scenario the game `quits unexpectedly` I seriously think about requiring a refund because I cant play the game. I play it on my brand new macbook pro retina so I guess the problem wont be the hardware. I am very very disappointed and for the price I would like some solution from the game creators because this game just does not work. Even while playing the tutorials the game quits unexpectedly all the time.
