The Black Simmer

I am just going to copy and paste what I post from the other topic that asked something like this. Hope this helps!

Your folder might be corrupted, did you update the Sims 4  (if you updated it) with the mods folder? I learned a while go that's one way it could not working. Other wise, I suggest making a NEW CC folder in the Sims 4 mods folder. Whenever you go cc shopping put all of it in that folder and then once you open the sims 4 and it does not work, then you know it's something in that folder. Just a suggestion for future reference.
