How can I play Gunbound World CHampion!?

Hey, can someone tell me if Gunbound WC is p2p? I had to register again but it was all different, it asked me for some numbers :S (lol) CFG or something like that O_ô... Can someone tell me how o register there? I tried but they say the number is invalid(wich I don't even know what that number should be :S )

What are those stuff they ask you to put as numbers? I don't get it :S... please explain or make account to my e-mail ^^ (j/k but you can do it if you dont mind)
