I have had this GTA 4 download on my harddrive for about 10 months. It didn't start freezing until about 2 months ago; at first it wasn't very consistent, a reboot cleared it up. For the past few weeks it has been freezing within five minutes of playing. I have tried clearing the cache multiple times, unplugging everything, and even redownloading the entire game, all to no avail. Connection to the internet does not make a difference, and other games play fine (games that are on disc). I feel rather cheated that my game isn't functioning, so if anyone has any ideas, I would greatly appreciate them. I want to try everything I can to get it working before I ... *shudders* ... call tech support.
