Are you trying to sign in? It should be working, I don't know why it wouldn't. It doesn't let you sign in, or anything that would connect out of the player, but you should be able to play.

They can't specifically says supernova can't sign in. Not a bug, specifically designed that way, but it does work, if you have supernova. You just can't sign in.
