Black Screen of Nothingness in Champ Select

Joined a game. Champ select comes... but doesn't. Just black. Can see the bottom bar, access friends list. Can't go to their profiles - tried that in hopes it'd snap the client out of the blackness. Waited for it to timeout. On my fifteen minute timeout because of the bug now, so figured might as well post it. I'm AN IP, one, singular, away from 6300 too. Torture.
