I just got the game yesterday and it loaded up fine initially. Played for a while and turned off the system like normal. Today it won't read the disk at all. The icon doesn't even show up on the XMB anymore. The drive just makes a whirly sound, click, whirly sound.
I tried using my other games. It works for 15+ other games and movies, with the exception of GTAIV, which I haven't played in a long time. Someone told me this was due to PSN maintainence, but nobody else seems to have this problem. Help plz? Thanks.
It has nothing to do with PSN maintenance. It is possible that your optical drive is having problems reading dual-layer Blu-ray disks, but not single-layer Blu-ray disks. That happens sometimes.
