Neverwinter Nights CD help



Ok here it is.

Im trying to create a backup/copy of my neverwinter nights play disk. Im using CD Version I write it as a protected game but when i try to run the game after installation it will not load. Im using a combo drive which came with the PC. I do not kknow which it is tho. How do i find this out aswell?

How can i create a working copy of neverwinter nights play disk. Please explain it in newbie terms and give me simple instructions please…

Thanks Very much
