Client Issue

Started to load into a game of ARAM and when I reached champ select my client was black. I could still see the minimize and close buttons as well as the chat and friends buttons. But the client was black otherwise. Had a friend in the game with me and he said that I had not selected a champ and the it looked like everyone else had loaded in just fine.

The issue was not with the internet because my friend and I were in the same room. Also just tried to load into another game and got a 10 minute wait due to leaver buster. I have left 3 games in 4 years. Leaver buster should be able to see that I had not loaded in at all.

Thanks.
