I'm receiving an error immediately after trying to launch LoL.
This seems to happen like...IMMEDIATELY. I don't even get to see the Launch button or the "League of Legends" loading bar before it just gives up. I'm honestly unsure of what to do...Uninstall and reinstall? But then again that'd mean I'd have to use the Patcher, which tells me to 
off before anything happens that resembles booting up.
