For anyone having the connection error/token error/wait for updated client error:
I had the same issue, downloaded twice, same issue.
Used my eyes to notice things and here's what I found:
There was a custom version set (Mine was set to 32.3.2 or something similar). To fix it, before clicking play click on the version in the lower left hand corner. Leav the box blank in the window that comes up and click set to set it back to the client's actual version and BAM - You can play again.
