i've never had any problems with any of my games but this one. in the middle of playing a game it will glitch out and say the disc is dirty or damaged (i just bought it new). one time it kept showing the same replay over and over which i couldnt end, and another it showed the players running to the dugout and just standing there which i couldnt end. i've played 6 games complete but its happened 4 times. what could be the problem?
