Hi. So that's what's up :
Everything worked good all day long. Tonight I went to a friend's place to play side by side and that's when I encountered my problem. I can launch the client perfectly and find a game. But, when the game is about to start, after the champions select, the game doesn't launch at all and I go back on the client where there's this button to reconnect. By clicking on it, nothing happens, I can try to launch it a thousands time, but it never works.
I tried all I could find on the internet (ultimately uninstalling and re-installing the game) but nothing works.
If you have a solution to this problem, let me know it would be really appreciated!
