Is there a copyright thing on The Sims Unleashed? I tried making a copy from my sisters so we can use it at the same time on both computers, but when I try to run it, it says "Please insert CD-rom." the file size of the burnt cd and the original is exactly the same. I don't get it. And if there is a copyright protection on it, does anybody know of a crack? Thanks. O, and if you need to know, I used CloneCD.
