gameguard 620 L2J

[calendir]

So, my friend has this problem when he tries to connect to my L2J. GG 620 error, something about hacking. He installed my patch (system and hosts file to connect to my GG emulator). Works for me just fine but he gets the error >.> Help please?

FIXED with old good hosts file...

I have exactly the same error! all av disabled, all ports opened, no firewall, I can play the game on my comp. but when my friend tries to connect over WAN in Character select screen he gets error code 620 or a hacking tool found bla bla...

Any pro to solve this issue???
