Does jfadeland show up under your main menu list? Because I can install all the worlds without error messages, but they don't show up in the Main Menu. They must be there, because I installed Arkham after I noticed this happening, and yet it works with a save file plopped in my Saves folder.
morriganrant, I will try your method. Cheers. I only need to use the .world file for this, correct? Right now, only Sunset Valley is in \GameData\Shared\NonPackaged\Worlds
Yep, just grab the .world file from Documents\Electronic Arts\The Sims 3\InstalledWorlds and drop it in \GameData\Shared\NonPackaged\Worlds. That should be all you need. I install them with the launcher, grab them from Installed Worlds and then drop them in the other folder. So far only EA worlds have issue with this, I believe this to be related to information the launcher puts in the .dbc files, that's just a theory though.
