I can tell the same thing would happen to me if I played there right now.
Notice how those tables at the top of my lobby have the little clock and they are pinned. I reg'd for these games. But it says 0 people registered and the lobby which I opened is empty. This was a tell tale sign that something wasn't right. 1 of the tables that filled I did get to play and it opened on its own but it still says 2/6 players registered and it won't update.
