twisted metal multiplayer help

[potatoman]

i have recently bought(preowned) twisted metal head on. i hear people always saying that all u have to do is type a username and password and it will say it is unrecognised and ask u if u want 2 make it one . i try this and it just says handle not recognised with this password. then it ´says press x , i do that and it sends me back 2 the password and username screen :eek: ! am i doing anything wrong? :confused:
im in the uk if it makes a difference.
