Abnormal Skin Import Problem

I have a very weird problem...

I skinned the Ilildian demonhunter. I imported the skin, changed path to Textures\herodemonhunter.blp, then saved. I closed the map and reloaded it.
I placed a demonhunter and the skin had not changed. I checked the import manager which still tells me that I have herodemonhunter.blp imported.

Until now I have been getting past this problem by editing the war3.mpq
to change the old demonhunter skin to my one. This works, but obviously i would prefer to do this normally, as it is easier & quicker to do so like this.

If someone could tell me my problem, I would appreciate it greatly.

Edit: And BTW, after reading Deathperceptions thread http://www.wc3campaigns.net/showthread.php?t=78679
yes it does work in-game by normal importing, but i still havent gotten it to work in the editor.

it is sometimes caused by having the same skin file in the warcraft III folder with or without a path similar to the one in the mpq

Yes, locally stored files with the same path will override graphics when seen in WE.

Check 1 - test ingame.
Check 2 - confirm texture path.
