Rockstar address GTA IV 'freezes'
With anecdotal evidence from internet forums suggesting that Grand Theft Auto IV might be suffering from intermittent crashes on both launch platforms, Rockstar have initially offered advice for PS3 players.
Forumites have reported crashes and freezes following the game's intro-sequence, and the publisher say that if this happens you should delete your game data and reinstall GTA IV.
Apparently, the problem is more prevalent on the earlier 60GB model console.
How widespread this problem is remains unclear, given the entirely unrepresentative nature of online communities.
