Improvement Pack installation help?

[rekijitsu]

The "Improvements Pack for Females" would be great eye candy, and I downloaded the most recent versions of WoWME.exe and MyWarcraftStudio. Problem is, I'm not sure how to get it working with the M2 files. I know how to get simple reskins working, but remodels always seem to crash the game for me, probably since the way I'm trying this, when I press F8 before the login screen, nothing "seems" to happen, I seen videos on how it was done in 2.4, and it took a while after pressing F8 for something to happen.

I tried making a patch-X.MPQ file using MyWarcraftStudio 0.10 and throwing in the Character folder and renaming the file as instructed. I made all 4 models in one .MPQ, but no luck. Also I can't seem to "preview" these models in MyWarcraftStudio, giving both Unknown animations and No Skin Found in the model skin area, could that have to do with my problems?

More info:

Altered character models. Modifies Model's breasts size.
-1 are a little bigger than default size
-2 are bigger than 1
-3 are very big
-4 are monstrous

REQUIREMENTS:
MyWarcraftStudio .10 to pack the files you want
ModelEditFix to enable model changing ingame

INSTRUCTIONS
-Remove each -# in the name of the model you want to use ( HumanFemale-2.m2 -> HumanFemale.m2 )
-Create a new Patch-Z.mpq with MWCS .10, (Z or any letter you are not using), in the World of Warcraft\Data directory
-Import the model/s you are using in the patch-Z.MPQ, keeping the path they must have ( Character\Human\Female\HumanFemale.m2 )
-Save the file and close MWCS
-Run ModelEditFix in World of Warcraft main folder

NOTE: MUST PACK IN MPQ YOURSELF.
