Seems NCSoft has removed the gameguard for at least now.
Not sure if intentional or mistake but gameguard is complete disabled from the client.
There is only a little client request at the moment wich will download the npgl.erl file which are only log file.
You can delete the whole gameguard folder / executable (GameGuard.des) and the game will launch only creating the erl file.
They also change the Themida covering the client.exe with this new update.
