Im a noob player that needs help please!

Hello Everyone! Buckey Ducky here and I need some help :) I entered into a match and we finally got started, as soon as we were at the loading screen before the game. It said to "reconnect" So I hit the button multiple times. Then after words I even exited out of the game, even signed out and restarted my computer. However all that L.O.L. shows is that I am in a match and won't allow me to do anything else.. what should I do?
