Just downloaded the new beta, Reconnect button doesn't work

I just updated the new beta version. So far 2 games have been attempted to play and both times - once all the players pick their champion and the timer is is up it shows an empty window with a reconnect button that doesn't work when i click it. My connection is fine and before this beta I never had a problem. HP pavilion if that helps but have ran lol on it 1000 times without any issues. Prease help.
