WE could not load models

WE could not load models

I downloaded the model file, extracted them and imported it into world editor but when I saved and restarted WE, it says "could not load file: war3mapimproted/XXX.mdl". The icon is working but not the model. I redownload the file but the same error occurrs. The model in WE shows a cube with black and green box. There is no pathway for the model in the webpage where I downloaded the model file. What could be the problem?

Maybe convert this model (mdx file) to MDL using this program:
http://www.wc3sear.ch/index.php?p=Tools&ID=3&sid=85ad478c63d7269ff90769323760f982
Then open the MDL with notepad and find textures used in this model it should looks like this:

}
Textures 2 {
Bitmap {
Image "textures\footman.blp",
}
Bitmap {
Image "textures\dust.blp",
}
}
check if all texturs egsist.

If one (ore more)textures is mising try too replace it by another texture (give it path of mising textures)

Maybe it will works.

No textures seem to be missing. By the way, the model is terran factory and terran factorymashineshop. All starcraft models seem to enconter the same problem. Can anyone help me?

I just found out I need to import all the .blp files stated. No wonder it isn't working before because I imported the one I needed for my icon. Now I can continue my map making.
