I had the mod working fine on EE, but after discovering that you can't edit classes with the SVN Access in EE, I got myself the Diamond Edition.
The game works fine, but all the PRC classes are blacke out, much like a prestige class you don't fufill the requirements to.
I think the problem is that no Documents directory was created during instalation for some reason? The override, database, hak, etc folders are all in C:\GOG Games\Neverwinter Nights Diamond Edition\
I tried both the manual install and the .exe install and no luck.
Any ideas? Thanks!
