i already have the original medieval II Total War game installed but then i just bought the Kingdoms expansion and when i pop the disk in the drive of my Dell XPS M1530 laptop, absolutely nothing happens. I hear the drive working a little bit but then stops after a few seconds, no windows pop up, no movement at all, nothing. And yes i already checked if autoplay is on and it is. anybody have this problem or know how to fix it? I already took it back to walmart to swap a whole different copy, but does the same thing.
