Serial/Access key problem

[blueicesolid]

Hello. I used my character on my friend's gamecube to play online. I entered their serial code, access key, and password when I was setting it up. Now, I bought a broadband adapter and I don't know how to change the serial code, access key, and password to my own game. Help!
