I am using another computer to play SK (since the other is trying to update but it takes SO long.)
So when I try playing it on the website it downloads very fast, then the screen blacks out (like it normally does when it's on full-screen) then it goes back to the original screen.
And the bottom tab (the thing with the Windows button (PC) doesn't show SK.
Also task manager says it's running but I don't see it.
I tried downloading it manually but it's all the same.

So what I'm saying is: What do you need to be able to play Spiral Knights?
(Java, Flash, ETC?)

Thanks.
