Ok, first off, i have Dotnetframework 2.0. Secondly i have my model edit in my data folder named EXACTLY "patch-4.MPQ" (without quotes).
I have my Model Edit Fix placed in my WoW directory along with wow.exe and everything else.
No matter how i start WoW with the Model Edit Fix. My character still looks the same.
I have the 2.4.1 fix and i am patched to 2.4.1 logging in to the live realms.
