I've been having a lot of problems in my game, the biggest one being unable to save after using buy or build mode, or edit town. At the Sims site they advised me to do a factory reset. I got as far as removing all the old saves, etc, and creating a new Sims3 folder (step 5 of the factory reset procedure described in that thread). Then spent a lot of time downloading everything from the Store again. It gave me the message that everything installed successfully, and I can find all my store worlds in the "Installed Worlds" folder. But the launcher doesn't seem to know they exist. When I open the launcher, the only worlds listed are the ones that came with the various EPs. Does anyone know what the problem is and what to do about it?
By the way, I have tried exiting the game and restarting the computer, which made no difference.
