Neverwinter Nights Premium Modules?

[torjusg]

I have problems authenticating my Premium Modules in Neverwinter Nights. It worked in Fedora Core 3. The game works otherwise very good. It lags a little when playing Hordes of The Underdark, but so it did in Windows too.

Does ubuntu come with a firewall? I use hp ubuntu if that is relevant.

Thanks in advance
