I have the same error. It is happening in DX9 and 11, and on multiple machines. This isn't can't be a software fault with my machine because the exact same thing is happening on a laptop that was running fine yesterday. This crash happened while I was trying to get through Raubahn. Suddenly I stopped being able to talk to him, and 30 seconds later the client crashed. I haven't been able to login since because the game crashes on load, but AFTER I wait through the queue.
