Re: Chicken Coop wont show up in game
@lilly_season Does the chicken coop show as installed in the launcher? Please check, and if so, uninstall it there first. Before reinstalling, go into Documents > Electronic Arts > The Sims 3 > Downloads and delete any instances of the chicken coop you see. Then download a fresh copy, install it, and see whether it loads in-game.
If that doesn't help, and you don't have a lot of Store content, the easiest fix is to reinstall all your Store items. Move the entire Sims 3 folder out of Documents > Electronic Arts and onto your desktop, open the launcher to create a new folder, download only the chicken coop, install it, and test. If it works, download the other Store items, a few at a time, and install and test them too. If your download speeds are poor, you can borrow the other downloaded files from the same Downloads folder instead of using the Store site.
If everything is intact, make a copy of the new Sims 3 folder—if your Store items stop working again, you can restore this backup instead of needing to reinstall everything again. Then move your saves and anything else you'd like to keep from the old Sims 3 folder to the new one. Here's a description of all the files:

Most of the files and folders can be ignored; the only ones you might want are those that represent actual content (e.g. Saves or Library), plus options.ini if you don't want to have to reset all your in-game options.
If you do have too much Store content to reinstall from scratch, let me know. There's an approach that may be able to save most of it, but it's a bit more complicated and somewhat less reliable.
