In the Halo 2 menu, all options are availible exept the LIVE and Network options. they are greyed out. It worked fine before, but then I got a new Mobo and processor, i didn't wipe the HDD, just cleared CMOS, so I think I may have to Re-activate Halo 2, like I had to do with Vista after the upgrade. Is there a way to do this without un-installing H2V and using up an install?? (stupid DWM)??

Iv don't think there is a way of getting it back up and running without reinstalling, but when I got my new Macbook Pro, I just called up Microsoft and they activated it for me... There is no limit to how many times you can activate by phone...
