unleashed backup copy for playing

[lakota1369]

I have been trying to make a backup copy of the new sims unleashed so I do not have to get the cd from the other computer in the house when I want to play as well. I have tried to understand and do what different progrms said to do with no luck. Any ideas what I am doing wrong? It keeps coming back saying insert correct cd and try again on each copy I try to make
