I am having the same problem except for that it is my CAS and collection folder downloads that aren't appearing! I have tried everything I can think of. It was working when I got seasons and then I had to reinstall it because my brand new computer (which is PC and I'm deffinately going back to a mac with intel because of all the probs ive had with it! I got it before mac intel and I wanted the sims expansions when the PC people go it . lol) was crashing every 15mins. That was when they stopped showing. I reinstalled again and it still isn't showing! Don't know if this is a bit different but I know how frustrating everyone is who are having these problems! If some one figures it out I will be VERY grateful!
Thanx.

I have a couple of suggestions that may or may not help, but I'll pass them along anyways.

First, I would suggest making sure that you have the most recent CEP (Colour Enabler Package), which can be found HERE.

Also, you should check to make sure that you have the necessary EP's/SP's that the creator is using. If the creator cloned a wall from Seasons to make their custom content and you don't have Seasons, the custom wall may not show up (which is why it's always advisable to use base game walls and floors when recolouring them for custom content).

I've had the same problem before, and I am having it now. The thing for me that worked last time was downloading something from the official Sims website (like the xmas tree or whatever). Someone told me that those were coded differently and would create the "proper" download folder. It worked for me that time, maybe give it a try I know how frusturating it is to have some but not all (or none at all!) show up. Good luck.

Sometimes they are binned in another type of wall or floor, but if they're not there, I would suggest clicking on the all (infinite) sign and see if they are located there.
