Didn't get lp for game.

Won a game 23/2 and as soon as i finished, league client had some error message and couldnt launch. Game link:http://matchhistory.na.leagueoflegends.com/en/#match-details/NA1/2134506518/220433851?tab=overview. Game showed up in my profile match history but not lolking and my lp didnt raise. Not that im desperate for 25 lp but i really dont like the idea of wasting 33 minute of teamwork for nothing.
