i've just about had enough

[Kamikazie]

Okay, listen...I have diablo v1.00(English) and i wanna make a cd backup. I copy it using NERO and it installs right and i put the PLAY cd in and the Autoplay works and shows the "Play Diablo 2" screen, I click on it and it says "Please make sure the Diablo2 Playcd is in your CD-Rom and Click on Enter"

I have tried many cracks and fixes but they do not work!!! I live in Australia, is there any difference???
