Halo 2 Vista Key

I've got exactly the same issue as above and have also just bought a new unused and sealed copy of Halo 2 PC for Vista from Amazon and after installing and trying to run the game I'm also getting a message that the Product Key is invalid - frustrating!

I know the game is old now but if the game is a genuine sealed newly purchased item then there's no excuse for the product key not working and I know loads of people have been having the same issue recently when re-visiting the Halo games back catalogue because release of Halo 4 has re-awakened interest in the series. Would be great if someone out there can help resolve this one. Harassment is any behavior intended to disturb or upset a person or group of people.
