Diablo 2

[ozziefire]

I have a question regarding backing up. I have followed the instructions on the website, but I have a problem with my play disc. When trying to play the game my computer doesn't recognise the play disc and I keep getting a message telling me to insert the play disc. I can sucessfully install Diablo 2 using the play disc to install, but cannot use the play disc to play the game. I was wondering if there was something I could have done wrong when backing up the cd, because I can play Diablo 2 using the original Play disc. If you can help me that would be great.
