Bug with login

So I was in a lobby waiting for my friends to come and then a message came on saying: "We have restored this installation to an older version of League of Legends. Now we'll try to patch it up to the latest version." then i need to click "Okay" and then there is anothere message saying: "There was a problem patching League of Legends. We'll restore a backup version and try updating again after you restart the patcher." and then I need to click "restart" and when I do, I recieve the same first message. And that the whole time again and again.

So please Riot fix this shitty bug, thanks [slayer-jinx-unamused]
