Update – Please see this post for information about fixing your Premium Content without a mod (if you don’t de-crapify): DCBackup, ccmerged.package and Your Premium Content Items
If you buy Premium Content from the Sims 3 Store, chances are that you’ve come across at least one seemingly broken feature of a “premium” object. Whether it’s the spell book and fountain of youth conflicting, the ladle for your cauldron not showing up, or if your sim can’t Pick Fruit from the Tree of Prosperity, the broken-ness of EA Premium Content is extremely irritating. If you’re having problems with any of premium content, I have a recommendation for you: the KT’s Store Fixes by kissingtoast at MATY.
There are several different fixes available in the thread, so read the details for each one thoroughly and choose the one(s) you need. You can install all of them, or only one of them. The most important thing you need to keep in mind is that you must have a ccmerged.package in your DCBackup folder, or in your Mods folder, or both.
If you don’t decrapify your Sims 3 packs, these fixes will still work. In some cases a fix is not necessary for non-decrapified content. For example, the Vintage Rotary Phone, which is a registration gift for The Sims 3 Generations, works fine without this fix (re-download the sims3pack if the phone doesn’t have a receiver). This won’t do any harm to your game if you don’t have a problem with all items, or if you haven’t installed them all.
If you’re interested in this fix, go ahead and download it from MATY. If you don’t know how to install package files, visit this link: Installing Sims 3 Package Files and make sure to follow the instructions step by step. If you do it correctly, you will be able to use package files in your game.
