Okay,

So my game has been crashing in buy mode - decroative.  When I play the game without enabling CC, I have no problem.  So, I start the process of weeding out the bad CC, but cant find it, I end up removing my Downloads folder.  This still doesnt solve the problem.  

I still have the choice to enable CC, and the CC listed on the opening menu are things I downloaded from the Sims Exchange.  Does anyone know if these are in another folder or how to get rid off ALL CC?
