Re: Sims 3 Store Worlds not showing up in game
@emmagr11 Yeah, that's why I asked—there's a bit more work involved, but it's not so difficult. The instructions are mostly the same, with an extra step, so I'm going to add that and just c/p the rest of the instructions, while (hopefully) changing all the tiny details that matter.
Trash the new Sims 3 folder you've created, the one into which you've been installing store worlds. Move the old one back into Documents\Electronic Arts, and use the launcher to uninstall all the store worlds that haven't been working. Make sure to remove their .world files in InstalledWorlds as well, if it doesn't happen automatically. Then move the folder out of Documents\Electronic Arts again.
Open the launcher to create another clean folder, but this time, don't install anything yet. Go into DCBackup and delete ccmerged.package. Now go into DCBackup inside your old Sims 3 folder, copy ccmerged.package, and paste it into DCBackup in your new folder. This file has a record of all the store premium content you've installed, and that content won't work without the file. So you essentially need the same one ccmerged file to be present while you install all your premium content. (If you don't own any other premium store content aside from the worlds that don't work, you can skip this step and keep the new Sims 3 folder's new ccmerged in place.)
Now install the store worlds one at a time, checking in-game after each one to make sure they're all still loading. If everything works, you can move the store content into your old folder. Rename the Sims 3 folder into which you've installed your worlds, e.g. "The Sims 3 Worlds." Put the old Sims 3 folder back in Documents\Electronic Arts, and move the ccmerged.package over as well, again into DCBackup.
Now go into DCCache inside the old Sims 3 folder, and count the number of .ebc files. (Now .ebc, with the e, not .dbc.) They'll be labeled dcdbx.dbc, with x being a number; the files are numbered sequentially starting with zero. (Ignore the .edbc files, which are custom content.) Whatever the highest number is, you're going to rename the .ebc file(s) in your Sims 3 Worlds folder in sequence. So if your main Sims 3 folder has dcdb0.ebc through dcdb4.ebc, and you have dcdb0.ebc and dcdb1.ebc in your Sims 3 Worlds folder, those two will become dcdb5.ebc and dcdb6.ebc. Then you can move them to DCCache inside your main Sims 3 folder.
Be sure to also move the .world files inside InstalledWorlds from the Sims 3 Worlds folder to the main Sims 3 folder. Everything should now show up in-game.
