World Tree Skin problem?

After I import this skin into a map, I can't put the world tree into it, how does this happen, I mean, it's just a skin, it shouldn't happen, the worst thing that could possibly happen should be that it got the wrong skin, shouldn't it?

Has anyone else encountered this problem, or could someone just perhaps test if it happens with their versions too, I don't wan't to reinstall WC3 just to find out that it didn't help, the skin is really simple, since it's just the same part for the whole tree, so I would really appreciate if someone could try it for me.

What skin is it, what path did you put it in, and where are you trying to place the World Tree?

I extracted the skin with Warcraft 3 Wiever, and copied the texture path, edited it in photoshop, saved as 32 bit TGA, converted to .blp, imported with the exact same path. Don't remember the path exactly, but think it was something like Doodads\Ashenvale\Structures\WorldTree\WorldTree256.blp.

Anyway, whatever I do to the skin shoudln't make the model impossible to place in the editor should it?

No, it shouldn't...,
Is WE crashing when you place it, or will it simply not let you place it?

It just gets the green/black coloured cube, as if the model didn't exist.
