Episode II?

Since I cant load the page for (the far superior) Episode II, and cant find it on the App Store even though I have the app on my device, Ill ask this here: the game (Sonic 4 Episode II) crashes as soon as it starts up. I see a black screen for a second then it crashes. Please fix it. I paid for that game, I will not accept being ripped off by not being able to play it.
