Glitch Black Screen and LeaverBuster for me

Ok so, I was playing a normal match, everyone was there, good ping and internet connection....we select the champion, we lock in and then we go. The window closes so the game loading match one can appear with the preview of who our enemies will be, but nothing happens, a plain dark screen. I wait for about 5mins and then I close the window and reconnect, but the same thing happens. The problem is that it's not my fault since the server did not give me any error messages nor any crashes, just plain dark and then leaverbuster low priority queue for 20mins. Since we established that it isn't my fault but it's the a game bug/glitch, could please riot remove me from the low priority queue? I haven't done anythign bad and therefore I expect not to be punished.

UPDATE!!! URGENT!!!

I did it again and same thing happened. What is wrong? will I not be able to play league of legends again??? pleaes fix this!!
