Here the counter for challenges usually resets at 03.00am, or 01.00CET, so 25min from now. I bet the client needs to be restarted after that for updates..
Edit. only the days challenge has changed, no signs of the game.
I think there won't be an update before 9 am today. IT guys like start updates when they are arrect.
This can't be a very good sign. Whole evening/night the client has needed to be launched two times to work properly First it's always a blank dark page after loggin in and then the tournaments info disappeared from the main lobby
