When I first tried to install DVD "My Computer" kept locking up and task manager could not even shut it down until I ejected DVD. I turned on auto-play and deleted all drives from "autoplaydisable" list. After reboot I tried again and it almost looked like "my computer" was going to lock up again, but the autoplay finally came up. I installed the game, it updated I registered and played for a while. The next time I had the DVD out to play something else, I replaced the DVD inthe tray and had the same issues as originally and haven't been able to get it to play since! ARRG!
