IIRC, you are putting it in the wrong place. I doesn't go under my documents---->Electronic Arts, it goes under my computer---->Electronic Arts. It is all explained in the rtfm.
I'm so sorry for all my confusion, I'm very technologically challenged. When I click on Computer-->The Sims 3, it brings me to the files that are on my disc. Are you saying I need to burn the files to the disc? When I try pasting the files there that's the only option I get.
