Can't join lol game due to directx bug...

I have been playing league all the day, then I go eat and came back to play, I launch a rank, got in champion select, the game start then... An unknow error has occured and League of Legends cannot start. Please make sure your video card is using the latest video drivers from the manufacturer... I was in promo for gold 3 and now I cant connect. Is it possible to get a lost prevented or something? I dont understand why it's doing this now, I played all the day and now I get the error...

Here are the proof of what happen... Match history to prove that I played today : http://image.noelshack.com/fichiers/2016/18/1462662364-history.png DirectX can't connect to league game : http://image.noelshack.com/fichiers/2016/18/1462662264-league-of-legends-cant-connect.png
