The game keeps crashing after champions selection (BugSplat)

My game kept crashing over itself 5 or 6 times after champion selection (just as the loading screen started) until i exit it, When i re-launch it, a massage popped up- 'Seems like some of your is missing, an update blah blah blah' And then, it starts updating, pretty sure the game is on right now and im gonna get leaver buster bullshit, but thats not the point......

Anyways...i guess i should report it here... i dont know xD..
