Specific Computer Stopped Running Roll20 Well

So I logged in to Roll20 on the windows 7 laptop I've been using to make all my campaigns on. I am using google chrome. So I log in now and over half the stuff I made in Roll20 has completely disappeared. I was panicked because I literally spent days programming all my stuff in and making the level. I have a ton of computers in my house so I log in on a different machine and everything is there and it runs fine. So it's not Roll20 and it's not my account. Something about my specific computer is causing the majority of my things to not show up, This includes things in my token library. I tried clearing my cache and logging all the way out and back in. None of this worked and here ends my knowledge of how to fix my Roll20 problem. I hope someone can point me in the right direction!

It might be related to the same issues of a few other posts about missing items, slowness, or graphics in searches being blank. My pages and items are loading veeeery slowly, if at all in chrome. I log back in using firefox and most of them load right away, but not all..but on neither browser can I add new artwork found outside of the marketplace. Try searching for a random token on web result. see if you can drag it to the page, if not it might not be your machine, but somehow linked to the same issue others are posting about.
