Assassin's Creed II problems..
Hi guys, I'm having a problem with Assassin's Creed II. I installed it on my Macbook Pro Retina 15" and the game doesn't work. All the things required are there... if it fully doesn't work, can I get a refund since I bought in on the App Store?
MacBook Pro with Retina display, Mac OS X (10.7.5), 15"
