League is connecting me to a game I already finished

So I was playing normal ARAM as this morning, a lot of feeders in team, you know, and when I finished I went into launcher and I was going to play another one. Here's the problem. LoL said that I can't make a lobby, so I restarted launched and guess what.. LoL was connecting me into that ARAM game I've already played as . In launcher it seems like I'm custom game, but I don't. In the game I have pure blackscreen, but in few second (+- 20) an error shows up that I have some problems with connection (you don't say). I can't quit this game, cuz when I shut the game down, only reconnect button is there. Anyone with same problem?
