Stubborn .mdx/.blp

Two problems here. First, I am trying to reskin a GreenDragon with a .blp file.
The new GoldDragon skin looks great on Image Extr. and on WCViewer. It's a standard dragon skin that has just been color changed. But no matter how I code the path (using the import manager in WEdit), NOTHING will get it it load onto the dragon with the new skin. It's always the old green skin. I have loaded plenty of other skin and model mods, but this one has me stumped.

Second problem is model related. I have models that work and look great on the WCViewer, but when imported by the import manager into a map, they don't show up (just the usual checkered cube). The model in question is a DoomWyrm (available in models section). If the viewer can see it and manipulate it, and I can import it, why can't I see/use it on the maps? There are a few other models that has this happen too. Also, has anyone been able to get the models available on MetalPlanet.org to load correctly? They look asesome, but no luck using them yet.

It turned out to be a (my) pathing problem and it's fixed now. Goldie is flying the skys of her map. But I still don't know why some .mdl's wont get recognized by World Editor when they can be recognized by WarCraft 3 Viewer. Should every model; not texture/skin, but model; be loaded into import manager as War3MapImporte\"modelname".mdx? I know skins and textures can vary their pathing quite a bit, but should every model be loaded like that?
