Hi, I don't know what i can do with an application that i have played for a few weeks, and all of a sudden, i can't open it anymore. When I click to open the application, it was black out trying to open the application. after a few seconds, i got kick out to the main menu. It feels almost like the memory is not enough to open the application. I went ahead to turn off and turn the ipad back on, but the problem still exist. What other method should I use?
