Backing up DVD PC games

Can anyone tell me how to backup my DVD PC game called ObsCure? I tried with Game-Cloner and the game installed OK but then when it asked for the serial number it said it was incorrect. Is this because its a copied game, and if so is there a way around that or isa there a better program to copy games with?
Thanks to anyone who can help. :slight_smile:

No it’s not because of the game been copied.
