For some reason the new classes aren't showing in character creation and I assume that any other new content won't work either. It smells of a dialog.tlk problem, but I put the included file in the tlk folder. Its been years since I've played around with this game, but from what I recall, all I should have had to do was to put the data into the override directory and then the dialog.tlk into the tlk directory.

[edit] Oh and I made sure that the only hak in effect is this one. There shouldn't be any conflicts.

Yep. Thanks, I forgot. Its been a while and I thought I remembered what to do.
