The first thing to do is to verify that you're adding the Mods folder (and everything else) to the correct Sims 3 game folder. Or I've moved your post to the Sims 3 PC tech section. Also if I failed to place one of "solutions" that didn't work for me above, bare in mind there were quite a few more, then, really, that's all I'm asking for. And I feel primarily this is the Mods folder's fault and if anyone has a better one than the one from Mod The Sims then PLEASE help and tell me by replying to this question. If you got this far, and I applaud you if you did, I want to specify once again that THIS IS THE SIMS 3 MOD THE SIMS FOLDER AND I HAVE THE SIMS 3 DOWNLOADED WITH ORIGIN. That and the fact it takes AGES to load for me to actually check and then I have to DOUBLE check in cas which takes a VERY long time. I've done the majority of things people tell me to do and every single time it hasn't worked. Delete and re-download the resources.cfg file in the mods folder Naturally, I searched it up to try and find a solution and I have done the majority of things people tell you to do: I haven't played the Sims 3 for a long time and I have it on Origin, anyway, I recently downloaded some package files for custom content and none of it is showing in cas and the "nointro" package doesn't work as the intro pops up and I have to click to skip. So you can probably already tell what this is about but let me explain because every situation is different.
