hi, i have an error when I try to use the sims 3 (additional disc called Super Powers). When I launch the game a pop up appears saying that no disc has been inserted whereas I did insert a disc otherwise I couldn't have gone that far to launch it. I just don't get what happens. Did anyone have the same error message ? is there something to do ? On a French forum I've read that a solution could be to download the game from origin's website but I already bought the cd rom and I don't want to pay again. Thanks for your help, Claire
