Mechwarrior 4 backup
 

I have a Yamaha 2200ez. i back up My copy of Mechwarrior 4 using Nero (came w/ my burner) it seemed to do just fine, it installed fine and when i tried to play the game it tells me to pu in the Correct CD... should i use another program, or is there other things that i have to do so that i can back up my copy wrighted games?

thanks in advance
