Issues editing a mod

[introvert]

i downloaded an armor and weapon pack the other day.  I noticed one of the pieces of armor was way over powered. i went into the construction set and edited it, saved my changes and went back into the game.  The armor and weapon mod pack was gone.

So i close out dump the mod back in and go back in game and its there again.  I again make the changes, load the game, and its gone again. I tried multiple things to get it to work not sure of what i'm doing wrong here.

I load the CS, set the mod to the active file, edit the enchantment and save.

Any help would be appreciated.

Thats what happened when I tried to make a ridable spider with the ridable dogs mod...

Sorry, I have no help.
