Client Crash During Loading Screen! [LEAVERBUSTER IS ON ME!]

After champ select, during the loading screen for the game, I have had four incidents where the client will crash (bugsplat) and not let me reconnect. I close the client and re-open it and it gives me a message saying I have some corrupt files that need to be repaired. After waiting about 5-10 minutes I can reconnect to the game. Leaverbuster has now set me into lower priority queue because of it. I have sent many bugsplat reports and nothing yet.
