[CLIENT] Blackscreen on champion select

I queued for a normal blind pick game, just me. Match found, I hit accept, when it's time for champion select I get a black screen. Friends list etc. still accessible, but nothing else.

I sat on this screen until I was booted back to the main client for "failing to select a champion"

I included a link to an image of what "champion select" looked like for me. I clicked around, couldn't interact with anything in the blackness.

Thanks for reading. Battlefight
