I just got halo 2 vista for my new laptop and i tried signing in and it said my product key was invalid. Even though online activation was fine I called MS support 3 -blam!- times and 1 was actually helpful and was about to give a new key to activate and then my phone dropped the call. So i tried again and 2 people told me the game is no longer supported. WTF do i do now? i got it brand new and sealed for $14.16 on amazon from a MS seller. But did i just basically pay that much for a paperweight? WTF do i do?
