Yesterday when I was playing Guitar Hero 3 on Bulls on Parade in the pre-verse, it kept replaying over the wah part throughout the end of the song and when it had the "You Rock!" thing it kept playing the beginning of the fire noise until I turned it off. So now it doesn't read PS3 disks and I just got Guitar Hero: Aerosmith. I got to playing the first song until it kept replaying one sound byte over and over and when I paused it, it froze. So any help, please?
