I have just started working with mods and such for Neverwinter Nights and can't get the races to work right. They won't appear in the "Races" tab when I play the game. Also, I have to play one of the classic classes before I can play any other "base class." For example, when I try to play a Ninja, I first have to take a level in fighter or bard or something like that.

I got frustrated and decided to start over and manually install the files instead of using the installer. That's when I found a missing file. The file's name is prc_include.hak. I have no idea if it's important or not. I can create a creature that with the races and classes in the toolset but not a PC. Am I doing something wrong? Does the missing file have something to do with it? Or am I just an idiot and missing something?
