It has been a long time since I have messed with them, So I am a little fuzzy as to how it all works.
The best I can do now is to tell you how to get a copy of the haks they use.
When you start a premium module, The game creates a copy of the Haks it uses into the hak folder.
You can open the hak folder while the game is running and copy the haks to another location so that they do not get deleted when the game closes.
