I am Japanese.
My name is Satoru
I live in Canada
Nice to meet you :D

...Oh, and I love anime. See?

Whenever I try and play multiplayer, or create a multiplayer match, while the match is loading, before it begins, this thing pops up that says "Your CD key is invalid." Why is it saying this and how can I fix it?

You might have accidentally typed the wrong CD key. You'll have to uninstall and re-install and re-type your CD key on the back of your disc case. Some letters or numbers might have gotten confused. Happened to me earlier.
