Steam not showing store previews?

I was going to look at some games which seemed interesting and when clicked on it no preview images or videos appeared. I tried restarting Steam and my computer, nothing changed and I noticed the popup which appears when starting Steam also is blank. (Images provided). Anyone know how to fix this? I tried clearing all html cache files, did the flushconfig, made sure my DNS is the Google DNS, and made sure the compatibility of it was set to run as Windows 8.
