Game Bug!

My account along with everyone in the ranked game is bugged, I had a victory screen the I clicked it and when I got out it said "Your game crashed" then I clicked reconnect and then while I was in the screen it was just black until I alt+f4 then it displayed the same message then I informed my friend to log into his account and see if the game was still in progress(spectate) and he said we were but he couldnt get into the game all he say was a "not connected" on everyone in the loading screen. Please assist me!(SUMMONER NAME: CLUMPNUGGT)
