I just downloaded the patch and no I can't play a game.
When it goes to the laoding screen, before the pictures of the heroes appear, there is a "ding" sound and the screen stays black for awhile. Then it takes me to the postgame screen where I have the option to wait for stats or return to the lobby.
If I go back to the lobby, and try to play a game, it gives me failure to join queue.
If I log out and log back in, then I receive the reconnect message. If I click on the reconnect message, then this whole process repeats itself with the "ding" sound and me being put back to the waiting for stats screen.
