Hey guys....so after updating my laptop from windows 8 to windows 10, League of legends login screen has been black. but after fixing it, after champ select, It says to reconnect and whenever i do click it, it wont let me join back in. I don't know if its the updates fault, the computers fault, or Ritos fault..... does anyone have an idea on how to fix this?
