I downloaded a bunch of individual CC and a few packages and they don't show up in game. They are all in the mods folder and I removed the extra numbers from them. All files are unzipped.
Can someone help me?
They may very well be outdated. I recommend you search online for something more recent there are plenty of places to get Mods and CC. Just remember that each time there is an update to the game you must ensure that they still work and look for updates.
