How do I get NWN multiplayer to work?

[Abdul]

I have tried using the Fairlight 1.19 server/client patch for Neverwinter Nights, but it doesnt seem to work. I can create a server fine, but when I try running the game with Fairlight's patch, it asks for a cd-key after the intro movies. Even when I enter a valid cd-key it gives me an 'invalid cd-key' error.
With the Deviance 1.19 patch I can get into the game and play single-player. But when I try to play multiplayer, it wont let me create an account.
Can anyone help me with this problem? Thanks.
