GameGuard Not in client anymore
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.
