So, I can't play League anymore.
I got the new client recently, and it worked psueo-fine. The right 20-25% of the screen isn't visible, which blew, but I was still able to load into a game. Cool. Game plays, I stomp, whatever right? I load into the next game, and I need new masteries. I go to edit it, like I do ALL the time, seeing as I have just 1 mastery page, and not only can I not mess with the resolve tree, but I can't close it. This results in me being unable to choose a champion, forcing me to bail from the ranked champ select. I have no idea why the new client is doing this to me, which sucks in it's own right, but I also don't know how to get the old client back. If I can't reverse the process league will become impossible for me to play.
