If you have another drive like a dvdrom or something, play it in there. If your writer is the only drive you have, download CLoneCD, run the clonecd tray util. Click on that and there should be an option to hide the ATIP code. This is what's preventing you from using your original cd in your writer, it's a little gift from those asshole publishers who hate their customers. You can use the clonecd tray util to disable the ATIP check, and in this way you may play the game. Or you can download a crack and use that (ironic ain't it ?
). If the clonecd tray icon is grayed out, set your country settings to another country like Canada. Or Jamaica
