I did that too. I downloaded them and then installed all. It unlocks and shows it's installed, but when I open the game it is not there. I bought Gothicue bedroom=office set for example and when I go in build mode, to select windows it still displays with the simeleon sign, when I press to download it it says I already have it. I am re-installing all sims games now, I am concerned maybe because I had all my CC there this caused problem? but I removed all CC and still nothing.
