Unitentional leaver.

So about 5 minutes ago i had to close out league and restart computer for some security purpose (computer restarts very fast) while loading into a game. well when i went to open league back up it logged me in and all it did was go to the "game still in progress" screen of the actual client. i could not get back into the loading screen or back into game and therefore marked me as leaver. is there something i'm missing to get back into game after closing it out?
