App Not Functioning

I am currently using a 32GB iPhone 4. As soon as I tap the app to play the game the app crashes. I have uninstalled and installed the app multiple times with Wi-Fi (I tried all kind of Wi-Fi carriers) and without Wi-Fi but the error still remains. & Seller/Developer of this app please try to solve this issue as soon as possible because I enjoy playing this video game.
