After applying latest patch (1.0.2.42192) I am unable to select my character on the character select screen. The screen itself is has no characters displayed, and seems unresponsive. Clicking on “create new character”, “start game”, or “change world” seems to have no effect. I am not able to exit the game normally from this screen and have to exit the game via task manager or alt + f4.
This happens when the servers are no longer responding to the client or are “out of sync” and the servers are sending responses the client isn’t expecting, i.e.: server crashes, restarts, patches being applied, or the like.
Just happened to me a couple of minutes ago. Alt-F4 and end task. Re-loaded battle.net and game, to the same blank screen. Gave it 2 minutes and it populated. Good luck.
Same problem here… @Blizzard please test your changes before live!
