Not sure if this belongs here, so move if it must be moved!
As a lot of you have noticed, the EABioware site is down. If you stored your CD keys on their website, you're probably never going to get them from there again. If you're like me, you've relied on this service for a good many years after new computers and such, and probably don't have the original boxes anymore. But your keys aren't lost!
In your Neverwinter Nights folder (mine, for instance, is: C:\NeverwinterNights\NWN) is a .ini file called "nwncdkey." This file will list your three CD keys. It is safe to open this (and any other ini files) in notepad. Copy down your CD keys and store them somewhere safe!
That is all.
