Game keeps crashing on loading screen!

Game keeps crashing on loading screen (around 40%), also it gives me an error message says "you have been disconnected please check your internet connection and try again" I tried everything on the internet; disable ip helper, repair the client, deleted LogitechGKey.dll and LogitechLed.dll. I also checked the firewall, nothing is blocking league, so please help. "It was fine before the update"
