Preview glitch in My CC

Hi, I have downloaded the beta and community version of Sims 4 Studio Installer and also had to download something called windows desktop runtime x64 (not sure what that is but the S4S Installer said I had to download it for it to run); everything seems to be running smoothly and yet for some reason I cannot seem to see the custom content. I initially downloaded the S4S Installer to delete some broken cc in an easier way but I can't see the cc itself. I also tried running S4S without the additional desktop runtime download and the same thing happened. Any advice? I've attached some screenshots for clarification.
