I must have thrown it out a long time ago during a spring cleaning, forgetting that the keys were on it and not the disk. I still have the DVD because I kept it in a CD spindle with the rest of my game disks. I'm pretty sure I don't have a proof of purchase anymore. Is there a way to recover my keys?
If you have nwn still installed there should be .ini file in your game folder with those keys.
I'm afraid you would need to contact bioware directly as they rarely frequent legacy forums or simply buy digital version of the game from gog.
