Not all CC shows up in CAS

Hey! Yesterday I got a new computer and I installed the base game and Get to Work from here again, and then started re-downloading all my CC and added some new ones. But now all of it doesn't show up in the game. I've tried A LOT of stuff, and no matter how much I try I can't find any CC that is causing the problem. I've been googling around like crazy all day, but still nothing. 

And also the CAS demo isn't working...it just loads forever and then turns black. I've repaired it around 5 times and reinstalled it, still doesn't work. So I can't connect to the gallery.

Help please!

You should probably ask the people who created the CC about it, if it's not all CC then message the person whose CC isn't showing up and tell them.
