My OS is windows 7..I have run as admin,have 1.69 crit update installed and I have restarted my pc..even waited 10+ mins in between server connects and tried different servers all with the same result..CD key already in use..My friend had this same problem and was fixed by a simple restart. any help would be great thx!
Actually I just went and checked the config file, it had the same default cd key as my frined, I checked the cdkeys in the notes accompanying the game in my account on here and they were different, I switch the keys in the config file for thsoe then poof, issue resolved both me and my friend were able to join the server game I launched on my pc.
This worked for me as well.
C:\Program Files (x86)\GOG Galaxy\Games\NWN Diamond
Was the path to get to my games files.
Once there double click on the "nwncdkey" file and replace the keys found in your GoG account
Log into GoG and select the NWN game. There is a "more" drop down menu that you'll click on then select the "Serial keys" option.
Just in case save the nwncdkey file somewhere on your computer before you edit it. leaving the original in the same place as it is.
Copy and paste each CD key (Neverwinter Nights, Shadows of the Undrentide, and Hordes of the Underdark) into their corresponding sections, replacing the old ones. NWN being number 1, Shadows being 2 and Hordes being three.
If game isn't closed completely do so then open the game and it should work. Did for me, haven't had the issue again thereafter.
