well the title says it.. it tells me i put in the wrong cd, even though it's the right one, and til now it never gave me this problem.. did this ever happen to anyone? and if yes, is there a way to help me?

Install or start-up?

 

Make sure it is disk1 and not one of the other 3...

it is disk one, and it's at startup. When i put it in the initial menu appears and everything, but when i press Game a message appears that says i put in the wrong cd

If you have 2 or more diskdrives is it in the one where you installed the game? Did you add hardware recently that adds an additional drive (harddrive itself or USB-stick or something like that)?

it happened to me lots of times, does it also come up with something about the sound or something? and other junk about microsoft? perhaps its because like HH said you have 2 drives, sometimes that doesnt work during insallations, you need to just use one of the drives

no i don't have two drives, and haven't added anything new.. i uninstalled it a few days ago, but reinstalled it yesterday.....this is so weird.. well u guys know any solution to my problem?

You installed it in the same map again? If not it might be a register error...
