Alpha client crash

My client crashed after champ select on the loading screen making me 15 minutes late into the match and forcing me into lower priority ques both of the current clients are terrible, I always get bug splats in the client on the loading screen so I guess this should have been expected. I've tried reinstalling and whatnot, lets hope riot can get it together and this client will be better with time as I'm sick of being punished (for leaving/afking) whenever I get a bug splat and it takes ages to enter a match once again 2nd time I've been punished for this.
