Druid form model change question.

[Druidking44]

Hi, I have Glitchy's MES and i have been having a lot of fun with changing the skins for my armor and mounts and doing race swaps but the thing i really want most out of model editing is to model change my druid forms specifically moonkin.

So basically my question is what program I need to get to create my own MPQ files for shapeshift skins because the ones i dl off of sites don't seem to work for me.

Also, i DO have the newest model edit fix for 2.4.2 and when i create my own race swap mpq's they work fine, however i can't get a single mpq that i dl to work, i always press F8 and load into the game and just nothing.

thx for your help =)
