Just installed GTA IV on home PC, registered online, downloaded all required software, installation completed. As soon as I attempt to launch the GTA IV game with CD1 in drive, I get the message: GTA IV FATAL ERROR: DD3D50. I am a new online user from South Africa and welcome your assistance. I am running from a Pentium 4, 3.4Ghz, 2 gig RAM, Windows XP Service Pak 3, Tornado NVidia GeForce Fx5200 256 MB video adapter, 24" HpL2208W monitor, 1280 x 1024 resolution, 38 Gig available hdd space available.
