At first, the game were running normaly (scuse my english, it's not my usual language..) but after I installed the update that Civ4 downloaded itself from the main menu, it's refused to lauch the game. So I tried to remove it from the control panel of my compu.. then I got the error -5004: 0x80041f42. Since that day, impossible to re-write the game on the prrevious one, impossible to remove it from the control panel and, of course, impossible to play. I didn't get in the files for deleting the game.
