Can't conect to server

Hello.
I'm using kubuntu 8.04
I downloaded the tar file.
I run ./update.sh
then i run ./client
I created an account In main server. But when i try to log
the response is " Unable to connect to server!"
and in console:

MyStarbox::Initialize
MyStarbox::SetupPlugin:initalising
MyStarbox::SetupPlugin:succesfull
Loading Star Calalogue:data/art/3d_art/environment/sky/stars-11252.txt
NOTIFY: handleStates: Loading Intro: empty
NOTIFY: handleStates: Clearing screen due to missing intro.
connect: Conexión rechazada
connect: Conexión rechazada

last part is "conection refussed"

If i try ./build returns

... ...Conectando a ftp.perforce.com|206.225.83.22|:21... conectado.
Identificándose como anonymous ... ¡Conectado!
==> SYST ... hecho. ==> PWD ... hecho.
==> TYPE I ... hecho. ==> CWD /pub/jam ...
No existe el directorio `pub/jam'.

+ die
+ echo 'died in script ./build.sh at line no 376'
died in script ./build.sh at line no 376
+ [[ -n '' ]]
+ exit 1

The error is "don't exist directry pub/jam "

what i have to do?
