I live in Santee South Carolina. And mine stopped working yesterday evening. It happened when I was patching the game and it just crashed. I rebooted then tried the launcher and it refused to work from that point forward. Well at least its good to know I am not the only one having the same problem. I hope it gets fixed soon.
I've wondered if I've got the same problem as you: after the patch had been downloaded, I got a message "Error 36: A file was locked that could not be open [sic] for writing." It seems to be connected with a "nvtt.dll".
