I'm currently on deployment and my fiance bought me a new copy of Halo 2. Installed fine, but apparently the cd key in the case is a bad key, according to halo. So I bought another new copy offline. Same freaking error message. So I'm done with that route. I can't call microsoft because I don't have a phone here in Qatar. Does anyone have a working cd key I can buy? I'd be happy to pay through paypal if I can get a working key. I'd rather not waste more money on buying a new copy. Plus, it took 3+ weeks each for the others to get here. It's becoming a giant headace
