I recently downloaded Gameloft NFL 2011 onto my ipod tough 4G. After the intro and just before the start of my game, the whole game screen shrunk to half the size and shifted to the upper left corner of my ipod screen. I deleted and re-downloaded it. This time, it happened immediately after the intro. I haven't deleted it again yet because I am waiting to find out if it was something that I may have done wrong. Currently, it is still stuck. Has anyone experienced anything like this? If so, how do you remedy it?
