Sims 2 mods and CC won't show up (Legacy edition)

Thats the thing, even IKEA stuff won't show up (it was the first thing I tried to add into my game). No downloads for add ons appear to be working in general so I can't even use IKEA because my game won't register it for some reason. I'm fine playing base game, so it isn't that big of a deal, but I know some people's mods and CC have worked without restoring IKEA.
