Here's the MPQ: Filebeam - Free Fast File Hosting
Here's what I did. By the way I had made this exact same edit a while ago and it worked. Can't understand why it doesn't work now... I extracted the model from here: patch.mpq CREATURE\FROSTSABRE\FrostSabre.m2
Extracted the skin from here: common.mpq Creature\FrostSabre\RidingTigerSkinRednosaddle.blp
renamed the m2 to CREATURE\DruidCat\DruidCat.m2, the skin to Creature\DruidCat\DruidCatSkinBlack.blp
packed it, called it it patch-5 and when I click play on the launcher, crash...
Like i said this worked before, and I recently (two day ago) used andrige's worgen edit for cat form and didn't use the MEfix.exe at all.
I think I'm just missing something obvious here, but can't figure out what...
oh btw, here's how it looks when I use WoWmodelviewer. This is exactly what I wanted to make, wowmodelviewer sees it, but wow crashes :'(
