Black and white

well im a newbie so what the hell. this game looked really good. but you know im poor. so i did the good old bit torrent and downloaded this game. and im not asking for any cracks or anything. but i did download it. i burned it on a cd. and then i installed it. but when i try to get it running it says i need to have the cd in. and the cd with all the stuff on it is in. does any one know why this is? because im completely confused. i really suck at computers and a couple of friends of mine diddnt know either. thanks for your help.
