I think this is not a new problem for you, but I really don't know what can I do. I read all the discussions about this problem and I tried everything. But nothing. I'm using Windows XP. I have 2 cd readers (one is D: and the other one is F:). Using D: the setup doesn't start but it gives an error in "setup.exe". Using F: the setup goes correctly, but when I launch the game, it doesn't happen nothing. Just returns to desktop. I thought it was a video problem: i changed resolution, installed the latest drivers of my video card (nVidia GeForce FX 5200) but nothing. Thinking it was a conflict with NAV, I uninstalled it, but nothing. So I downloaded the setup fix, I reinstalled the game with it, but when I launch the game (the fixed exe) with the cd inside the F: unit it gives me an error in "game.exe". In addition, if I launch the game with the cd inside the D: unit, it doesn't want to start. I think there's a problem on reading from the cd units, but I don't know ho to solve it. Attached there's the DxDiag file (edit: the right one is the PMDxDiag1.txt, sorry). Thanks to everyone wants to help me. [attachment archived by Gobalopper]
