Ok odd thing is I lost the little thing the CD comes in that has the CD key but I have the CD and box.So if anyone isnt playing Halo and is kind enough to lone a CD key I will be gratly appreciative.If not then I will just have to buy another one i suppose.

Sharing CD keys is illegal, you should contact the publisher with proof of your purchase and have them give you a new key, they usually do when you provide proof of purchase.

Yup, agreed.
