Hello!
I´m new to this game and i have 1 or 2 questions:

I downloaded Gunz but when i started it, and entered my gunz id,which i made on GunZ The Duel: International Edition, it said that i couldn´t connect...so what could i have made wrong? is the id i entered the right one, or do i have to make somewhereelse another id?
then i deleted this version and downloaded another version. After I installed this version I wanted to launch the game and when i launched it, i came to the internetsite from ijji, where i should click on "play now"....So another question is, is there a difference between the "ijji-gunz" and the "other gunz from gunzonline"? if yes, what are the differences? please help me out in this, im a big noooob.

Thanks!!!
