OK.... so I got Child Of Eden yesterday, put it in my 60G XBox360, and it seems to try and read it for a second then says "Open Tray".... My other 20 or so games ALL work absolutely fine, but this one game just won't work. I tried it on a friends XBox360 and it wouldnt work on his either, but then I took it to work and tried it on an Arcade console AND a slim console, and it worked fine on those..... Is there maybe an update I need to do to play this game? Thanx!
