I download the Sims 3 and i want ALL the expansions. How do I do that? I know how to do one expansion pack added to Sims 3 but more than one has me confused because I do not know where to copy the crack to....do I copy it the previous expansion game bin or do i copy it to the original game bin file? Do I use it like stepping stones? Sims 3<supernatural<ambitions<High end Loft< ETC...
