Since nexon successfully IP banned you, that means you must have a static IP.
As long as you are IP banned, any account used on your comp will be banned. You have to change your IP, by one of the methods above. If they don't work call your ISP and ask them to, but you have to create a good bullshit reason, for they won't do it without an explanation, and won't do it to help you get unbanned from a game.
