Need help Simcity 3000 Unlimited
 

I have tried to make a back up of Simcity 3000 Unlimited (US). I get an error when I try to play it. It says incert the correct cd. I have tried cdclone it does not work with my cdrw. I have a compaq computer. I know bad on my part!!! Does anyone know what I can use other than cdclone since it won't work for me? New at this never had any probs doing this sort of stuff.

Would someone please help me on this topic.
