The World of Avlis

I tried to join an avlis server and i have the password but is says i am missing some file and i have installed all the hak packs and i have updated nwn so what could be the deal? is there a hak pack i am missing and if so where is it?

You'll need the Avlis hakpaks to join. Some are rather large:
portal.php?getpage=hakpaks

its should tell you what you are missing when you fail to log in.
