My champ select is glitched?

So I started a ranked queue and found a game. While in champ select it told me I was disconnected from the servers even though my music and skype call were still going on. All of a sudden my game went black except for my friends list and messages. If i click exit it says i will lose lp even though i can't do anything. I don't want to be in negative lp for something I can't Control, please help.
