To all Ipad2 users, Have you encountered this on your device? I just downloaded and install "National Geographic: Ultimate Dinopedia" and when I open the app it keeps me spitting out of the game.. I tried this for about 10 times and I keep on downloading the app and installing it but nothing happens.. Please help me.. There's no other application running.. File size is 390.1MB Please help me.. It's for my son..
