I tried to follow Crinrict's guide,but it is out of date, the links are broken (purchase history). I successfully installed one world, but cannot get it. She said that it will credit sim points to you and then you're supposed to download it and that the "price" would be the same as what they credited you with. I didn't find that to be true. It credited me w/only 500 points for Hidden Springs, but the world costs 2000 points in the store! In essence, I would have to buy more points in addition to having bought the disk! I'm not sure why they made this whole thing sooooo complicated! When I tried to redeem Monte Vista according to the directions, I got the msg that it (the code) had already been used. Well, yes! I want to re-install it, but I need to enter the key code to re-install it. So now I'm up against a wall. Maybe I'm just not understanding it correctly. : /
