I bought a brand new copy of gta4, it installed the game data then froze during the opening cutscene. The audio kept playing. I deleted the game utility data and tried again, it did not work (i did that three times). I have the launch day 60gb ps3. I installed my own 160gb hdd, not sure if that matters. Anyway, I can't get Past the opening cutscene or play the game at all. Help!
