Copying PC DVD-ROM Games

HI,

im trying to backup my copy of Black and white 2 which uses safedisc 2/3
This is my first time trying to backup a DVD-ROM game
I have previously copied CD-ROM games no problem with Alcohol 120%
But when trying to copy a dvd game with Alcohol it doesnt give an option to chose which protection the game is using.
I copied the game anyway and the autorun worked fine when i inserted the backup but when i clicked the PLAY button on the autorun window it said: “please insert the correct CD-ROM”
Could this have anything to do with the fact that i installed the game with the original DVD and im now trying to play the game withe the backup?

Sorry about the very long post!!!
