Hello, Iam before x. years got halo 2. Successfully activated and played. But I lost product key, I installed game from the CD and cannot sign in into Windows Live account. Because it want product key what i dont have. I contact Microsoft support and they sent me here. There is some Reference ID: 1257893109. They said I don't own this game. But (according to them I dont own 6 games). When I loggin into game i see in game tab all games what I have. Too same on my social profile. Is there way how to get back my product key what is connected with my windows live account?
