Ok I have to step in here for a moment. First of all anyone who plays alot of games on a computer will notice most games come with a cd-key and they codes are all different. Second of all how can you lose a jewel case but not the cd that came in it? I have used many cd games and have not once lost the cd key for the game and I keep a record of my cd keys in case the key becomes faded to the point i can now longer read it. i.e: my diabvlo 2 cd key the key is so faded i no longer can read it. Well that just my 2 cents.
