I cant Update League

So i just tried to start up league, and the launch button didnt show up for 5 seconds. Then before it shows up the Disclaimer thingi shows up, and then the orange button shows up. If i click it nothing happens and it just goes orange again in 5 seconds. I completely reinstalled and it didnt work still. Repairing does nothing and it still just shows the launch button. Pls help

Edit: Deleted my entire Riot games folder, seemed to work for now. Lets hope for the best
