Maybe try re-dl the entire client from the ‘Download’ tab (newly updated on 2nd November).
The error is partly due to too many model files (or something like that), which causes the client to crash just before entering into the game.
You may read more to understand under the comments section of ‘Patch V71’.
I’ve re-dl the new updated client as adviced by inf and everything is fine now.
P/S Verifying the client will not work (at least not for me).
