certain sim cc not showing up help pls

[rufuntoplaywith]

so i just got celbration stoff pack and installed it yesterday i also installed my seasons pack after that. i made a back up of my downloads and then deleted the old folder. Now i put the new DL folder back and re opened all the download files i have. I know not all the CC will be compatible with CSP but why is it that the only stuff not showing up is all my body shop CC??? all of the buy mode and build mode stuff is. I can't even download some new skin or hair because it isn't showing up ( i know this because i tried already). someone pls help me i need to customize my Sims:cry:
