I downloaded the game and tried to launch it. I'm on Win 7 Home premium and when I launch the game there's only a black screen and the music, I also have to close the game with task manager. I tried to use the win Xp SP3 and running as an administrator both Gp4.exe and the Gp4 patch application(which also has the debug mode and extended time period on) but the result is always the same.by IlBecchino - Grand Prix 4
