Character stuck in game long over?

I was in a game and it locked up, entirely. I thought the server was going down or something. I closed out the game and restarted, trying to get back in, it said it could not connect. That was over an hour ago. Now every time I try to log in it tries to reconnect to that game, which obviously has to be way over (it was ARAM), so currently I can't do anything but repeatedly try to reconnect to a game that isn't there. I have restarted the game, my pc and everything else I could think of.
