Hello, I am trying to use booster prime to optomize my League of Legends and it was doing it fine yesterday but today I am getting this message now: We're unable to optimize your settings as your game might still be running and or it's settings file is in read only. Please exit the game and/or it's files attribute and try again. I've exited the game completely. It's not showing up on my task manager. Can somebody help me please.
