So i already completed the game 3 times ! On my third playtrhough when University chapters starts i can play the game normaly, but when i open the first gate to go to the generator the voices dissapear ! I see the subs of ellie talking but i won't hear a thing, neither from joel ! I didn't pay attention and gone to the panel to take the artifact, but after i take it i cannot read it, again didn't pay attention and gone to start the generator but after i start it (i can here the sound of the generator very clearly) nothing happens the infected won't appear and even if i go to the door it won't open ! SO i restart the game but nothing, now i cannot evenload it stucks on the loading screan and the loading on the bottom right won't appear ! I tried torestart my ps3 i deleted both the games install and patch also cleaned the disc for like 10 minutes , but nothing ! ( I also couldn't load any chapter from chapter selection ) So i ust started new gameit loaded perfect no glitches or bugs appeared .... until i got to the University ! It bugs in the exact spot with the exact same way ! What to do ?
