modifing data files for SW

[Geewaagh]

I am having a little problem getting started and was hoping someone could help give me some pointers.

I have the authoring kit and I am trying to add some new equipment and skills to the SW data source files.

I made a copy of the savage worlds directory, named it something new. I am opening the thing_armory.dat file, adding a new armor entry, then trying to save. It tells me the file I am modifying is not read by rule set. Also, when I do a "save as" it is wanting to create a .user file not a .dat file.

When I force the save, I can see it in the list if i open the file again. However, I can never see the item in the armor list when creating characters.

What am I doing wrong?
