Client Bug - Unable to join queues

When I click play and look at queue options, I'm unable to select anything other than blind picks for Summoner's Rift and Twisted Treeline, ARAM, and ARURF. All of the other queue options (ranked, etc) have an error by them that says "Trouble fetching information for: Nefas. Affected players should quit and log back in if this persists. (5C)." However, quitting and logging back in doesn't do anything.
