Modding Armorgrp.dat

[L2Italia dev]

Hi, Guys, very nice forum!
I have a problem:

I need to mod a non ufficial armorgrp.dat file
I can decrypt it with l2encdec.exe (all ok)
but i cant edit it with L2dat_full.exe, it give me an error (An unknow error accured while accessing etc....)

How i can solve that problem? I need to make only a simply mod to this file:

I see a special armor with 'blue wolf armor textures', i want to see the same armor with a 'tallum armor textures'.

Can anyone help me please? I will be very gratefull.
