So this never happend to me before. I downloaded PBE yesterday and started it today normally then i started a que for Nexus Siege ( does not matter) got into champ select picked my champ and then thigs started going down. ...prepare yourself the battle is about ot begin and then a black screen for 10 mins nothing happend i started task manager and needed to close lol client with it cause it wasn't responding. Opend league client again and it immidiately threw me to the log in screen nothing launch or anything and then it said Maestro error... restart client. Did it 50 times nothing, deleted avast nothing, turned off firewall nothing, restarted computer also nothing, run as admin nothing, reinstalling PBE client 3 times still nothing.
