Step 1: Go to the SwContrition website listed as the official page on this mod.
Step 2: Register with the forums. Currently Account Authentication is being handled manually due to issues with phpbb3. Authentication can be anywhere from immediately or within 6 hours.
Step 3: Navigate to the forum "Setup & Files", and select the topic "[SETUP] Server Files"
Step 4: Download all Files on the first post. You may not need to download the NWN Critical Rebuild if you have already, same with the Community Expansion Pack 2.3.
Step 5: Place all Hak Files in your Neverwinter Directory's Hak Folder. Default for this is C:\NeverwinterNights\NWN\Hak
Step 6: Place all Music Files in your NWN Directory's Music Folder, Default for this is C:\NeverwinterNights\NWN\Music
Step 7: Place the TLK File in your NWN Directory's TLK Folder, Default for this is C:\NeverwinterNights\NWN\tlk
Now you're ready to go!
Now launch Neverwinter Nights and select Multiplayer, and log in with your username and password. Allow the authentication server to fail and click OK. Now you can find our server under the Roleplay tab, or, use Direct Connect by pressing the Direct Connect button on the bottom of the Server Browser window, and type in "nwn.swcontrition.net" as the IP, without the quotes, and you're good to go!
