The game doesn´t work anymore (important)

My game crashed. So I forecfully shut my pc down since there was no other way of fixing it. Then when I re enter League the game client greets me with the new player screen and asks me wich region I wanna play in. I then quickly pick EUW and come back into my game but I can´t reconnect. The game tells me files are corrupted and the client hast to fix them. Now here I am with the client repairing itself and still being at 0.00 MB after 3 minutes . I personally demand you remove the leaver buster from me since your client just threw me out of my ranked game.
