Hello folks, I found my Halo 2 Vista the other day and I tried to play it. However every time I start the game up I get an error message, something about there was an error activating it. Whenever I try play Outskirts on Campaign, I get a message telling me I need to take the disk out, put it in and then play it for the activation menu. The only time I have seen anything about a Product Key is on Games for Windows, however that wont connect to the internet. I have tried to open the ports needed and still no luck. If it helps any I also tried shouting at it, That also was unsuccessful. Thanks for reading and please help.
Operating system: Windows 7 64 Bit
