I downloaded Stand O'Food game from app store on my dads mac book pro late 2011 4gb ram. Free version not 3 but the original. I mastered the tutorial and then it froze and unexpectedly quit. I reopened it and it quit again. I deleted it and re downloaded it from the app store. It quit again even after a reinstall and open first time after re downloading. It just unexpectedly quits. It refuses to open. Any ideas??
