Problems with the DMO Pack Manager and Nifskope

Note* The game in question is GDMO = Global Digimon Masters Online from Joymax.

Does anyone here know how to update the freakin' EDMO/KDMO.dmop files?
Every time I try, I get this annoying error message:

An exception occurred.File='src\file\dmopmArchiveFile.cpp', Line='118', Reason='Invalid File Format'.

(Same thing happens when I try to Map the directory).

Here are the pictures showing my DMOP configuration:

Clik here to view.

I have watched every and all Tutorial videos on YouTube about Texture modding but, not one of them shows you their configuration... -_-

So, if anyone here can help me out...that would be MOST appreciated!!

PS:

If&when I manage to fix this problem my next question will be: "How to configure Nifskope?"

(Again, NO ONE shows you anything!! They all just either show how to import the pre-made textures
or show how to mod them but WITHOUT showing us their configuration!!)

And if you ask a question about what I just wrote they will either:
a) ignore you/dodge the question (possibly due to their own ignorance about the problem)
b) call you a NOOB
c) give you an answer that only confuses you even more!
