Hello!I own a copy of Nwn and would like to play online but I dindt bought it from Gog so how do I submit my CD key so they know that I have the game and give me a Multiplayer key?

If you didn't buy it from GOG, why would you ask GOG? Contact the company you bought the game from.

Is there a reason you cannot use the keys that came with your game? Is it a CD or DVD version?

I think, You must consult the company which you purchased the game. They provide the best and clear details regarding this after you may contact the GOG.

Just so you know you should be able to use the CD Keys you have to play multiplayer if you purchased it as a DVD or CD, if you downloaded it from somewhere, you need to contact that source to get legitimate unique keys.
