I have been recently disabled and flying a wheel chair these days, And my question is I had found some of my old Micro Flight Simulator X and Gold Edition, and I want to fly again Can I still find a XP PC to play these sims again or have one built to play them again, and my other question is can I still use the old key codes for these games or will I have to buy new games with new key codes...? Thanks Armadillo Zack
