NWN - Private Server Loader

[CSeymour]

It's been quite a while since i've played this game- just reinstalled the NWN Original Campaign, SoU, and HotU. One of my roommates also wanted to try it out, so we tried setting up a LAN game after installing it all on his computer too. Obviously, we're both getting CD Key Authentication errors, etc, etc.

I've tried all the methods i can find to get LAN play to work (except blocking access via a firewall, as i'm not sure how to do this with the standard Windows SP2 Firewall):
- Editing the hosts file
- Using the Private Server Loader (which i found on GameCopyWorld)

We're able to get a game setup, loaded, and logged in on one computer using both of the above methods, but neither of us can find/join each others games- not via the Direct Connect feature or simply refreshing the LAN games listings.

We're both running SP2, have all the lastest updates to Windows, all the updates to NWN and the expansions (v1.68), and are on a wireless network through a Netgear router.

Anyone have any ideas on getting a LAN game setup? Or does anyone have any working instructions for v1.68 that maybe i'm missing in my previous attempts? I would REALLY appreciate it!
