Problem: The game starts normally but nothing has changed, it is like the mod is not there.
Reason: The game does not load the NTF.pack
Solution: a) Open user.scrip.txt and make it in Unicode format. b) Make NTF.pack a "movie" type. To do that:
Open [NTW]\data\NTF\NTF.pack with PFM. Click on Choose a Pack Action and mark movie. Save as NTF.pack in your desktop. Then take it and copy back in [NTW]\data\NTF\ replacing the older NTF.pack. Try again. Now it does not matter if you edit user script, since the NTF.pack file is a "movie" type, the game will be forced to load it eitherway.
