I'm really sorry to report but the problem is that when you each play the game, the servers think you're both the same person because of the CD Key being the same. The only wany around this without having to buy a whole new computer is to purchase a new copy of NwN and it's expansion packs (I think it's pretty darn cheap by now). Don't install the second game, all you need from it are the CD Keys. Simply go into your existing neverwinter nights installation directory and you'll find an nwncdkey.ini file. Make a backup of that file then open the original up and change the CD Keys to the new ones you've purchased. Now start up the game, login, and go rest somewhere (and play too if you like :P ) so that your character gets updated with the new CD Key info. When the other person wants to play, simply rename the nwncdkey.ini and put the backed-up one back. Switching between the two shouldn't be *too* bad of a nuissance considering it's cheaper than a new PC.

Hope that helps!
