Critical Error crashing my whole Pc not just this game.

I would like to talk to a riot employee about my game getting a critical error and not being able to get back on to the game until that game was over. This has also happened to three friends of mine however they could get back into the game once they had re-logged.

Also, I'm being forced to click I agree to not going AFK in any more games when I haven't gone AFK through any fault of my own so id like a riot to send me an emailing saying they agree to not do me over. But seriously can you sort it out and get this message off my screen because im not typing "I agree" and if im gonna be held hostage with that message and be unable to play so be it ive legit only had this game a day and i only got lvl 9 and this has happened jesus .[slayer-pantheon-popcorn]
