Sorry! We´ve detected a problem with your installation.

"Sorry! We´ve detected a problem with your installation. We will now attempt to repair the affected files." That is what my Client is telling me every second game. Whenever i let it repair itself it just happens again. I tried to reinstall the game for the 3rd time now and im tired of it and League of Legends itself. I got a leaverbuster now aswell and lost tons of LP. This started happening to me since the last few patches.
