Can't create/join games, even single player

So is something broken with diablo? I cant join or create a game, it says only the party leader can but I am not in a party. Whats goin on?

Is the Start Game button greyed out ?
Are you getting “Error 315000” ?
Have you received a “silence” (or mute) in any of the Blizzard games ?

If you have not been silenced and are getting Error 315000, there is some troubleshooting you can try here: Blizzard Support - Error 315000. If that doesn’t work, contact the Account section of Blizzard for assistance. Put details… lots of details… most people who are getting this error have received a silence in a Blizzard game or another… you will need to make it clear that your case is different.

If you have been silenced… this is a known issue. There is currently a bug that prevents players that have received a silence from starting a game or joining one. Blizzard is aware. The last update on this issue is here: Start Game Greyed Out - Unable to join game, only available to party leader - #455 by Drakuloth.

There is a topic in Bug Report forum that you can monitor for news, here:

There is no workaround that I know of… once your silence ends, you should be able to play Diablo III again.
