Edit dress .ddj

Hello brothers, i need your help.

I edited Koreandress (change color) in photoshop png > convert .ddj files
but i recieve client crash error, how to edit dress without error crash ?

USE DDS DDJ Convector
to change the photos from ddj to dds
Then USE Paint.NET to make it ddj again
Import and u're done !

You can still use photoshop for it, just the file convert should be progressed with the respective too, which you can find here on the forums.
I edited iSRO files back in 2009. Changing Kangsi's white skin to a proper tanned skin. :)
Works flawless.
