Livery - Unity Web Player Problems

Hey I'm not quite sure if anyone has had this problem before, but I'm trying to change my livery on the computer, so I downloaded the Unity Web Player, yet in firefox it says I still need to download it even though I have already done so. When I switch to IE, it does have it but all I get is black bars (picture included). Do any of you guys know how to fix this?

Thanks!

It works fine for me in Chrome and IE11. have you tried switching it off and back on again?

That shit always works, if that doesn't work you better give up XD

I have this problem:

"failed to Update Unity WebPlayer" 
And in the Error Details Contains: "A newer Version of unity web player is required" "Install it manually"

But i downloaded the latest Version of this from there Homepage. 
I try it with old Firefox, new Firefox, IE 9/10/11 and Chrome all the same error.
