Locked out of game after crash.

Client says "Game is still in progress..." but wont reopen the game itself. I was just trying out Senna in normal game. It's one thing that game crashes so hard that I have to restart my computer it's another that I can't get back into game after I restart. I relaunched the client 3 times with no luck. I hate to sound like one of those people but this IS the definition of "unplayable". Hope this doesn't happen in ranked.
