Huge Problem

Well, ive downloaded and installed the client 3 times, and followed the guide. i did use the patch aswell. Now every time i open the Launcher and hit start or w.e, it goes to "Yedang" then it shuts off my computer. Why is this happening? this is a game client, it shouldnt shut down my computer unless its trojan ridden. usually when something force-shutdowns a computer, its to stop it from getting viruses.
How do i fix this? all im lookin for is a good server, finally find one and this happens. anyhelp?

OK so i fixed that by switchin "Server 1" = "127.0.0.1" to "server 1" = "221.234.43.133" but now, when i get to the login screen it just keeps hitting login and i cant type my id or anything. whats with all these glitches?

i have gotten to the login screen but it keeps trying to login and i cant do anything. the "connecting to serrver" comes up, then "invalid user" comes up and it keeps that cycle. how can i fix this? my computers shut down 10x+ and the times i get to login screen it just keeps trying to connect before i can do anything.

I'm not really sure if I have understood your problem. But you have to click on a field for "Full Mode" when you open the Launcher. When you don't click on Full Mode "On" or "Off" your PC will log you in automatically when you start the game. Just make a Click at "On" or "Off" if you want Full Mode or not.
