Cant lock my champion in champion select/Timer stuck at 0/Cant press Ready/

Hi there, i dont know if other people have this problem, but i do. You see when im in champ select i try to click a champion, but nothing happends. When i have to ban a champion i press for example Camille but nothing happends after clicking to ban her a shit ton of times. And then you might saý: 'Your connection is trash, blablabla'. Well it isnt my connection since i have 16 ping in game. [slayer-jinx-wink] So if anyone knows a solution please share it with me btw its the Legacy cilent Greetings, Faantjuh
