100% loading, the game won't start until lol reset!

So basically, started a game, it started loading pretty slowly. After hitting 100% and waiting for like 5 mins, nothing was happening, so I reset lol. Clicked reconnect, but it said the game has ended, and a second later, that my lol version is old. Got it updated in a second, and saw I got leaver.. wtf? Twice this has happened to me now... Any help?
