Will this work?

Ok, So I ordered the all in one 2004 disc for ps2 for Japan. I also have the PC japanese version. I currently live in the US, and so I used the japan registration code to install the game. But for some really strange reason, my debit card wont work. So what I'm trying to do is get the AMERCAN playonline install disc and install that to get my billing info and everything normal. After that, is it possible to play the japanese ffxi? I have no friend who has the playonline (US) install disc for the PC. Thats all i need right?
