Having a problem

So I launched League w/ the new patch 7.10 today and played a custom game for a bit. After, my friends and I got a 5-man party for an ARAM, then when it came to the percentage screen, I failed to connect saying that there is an error saying something about something about the my drivers in which I found bs because i was just playing. I restarted everything and launched the client again and now I can't even log into my account(s).
