I was playing soul calibur 4 and i was doing a break to eat something and when i was back the game was stoped right there that i was left it and didnt loading.I was put out the game disc and the system was trying retrieve in the home screen but it was not loated and late for some reason.So i was turned off the system from the main swich...(the game was running when i was doing the brake) and im not left it for to much hour,it was playing about 15 minutes when i left it alone.And now the game discs that i put inside was readed normaly but when i am going to start the game it doesnt load at all or goes blank and stop playing.I now strarted format on the drive and i hope to see some light in the tunnel.
