Ok, the first thing I see is nothing, because you didn't provide the textures for the model to be seen, but I also see that some of the textures imported are in png, and not converted to blp, and that they are not even used along with the tex2.blp and Replaceable ID 0, so delete them because they take unnecessary space, as your model already has whopping 1.8 MB. The model size is due to the enormous amount of vertices, edges and faces used in the model. This is very unnecessary for such a small and simple model (of a cup, as far as I could see), and you should drastically decrease the amount of them used, because your model takes one fourth of the allowed map size limit for playing in multiplayer, and many much more complex models don't have even one tenth of the file size your model has. Warcraft doesn't require such detailed models, and they are even too detailed for this game.
Furthermore, one of the Material Layers has transparent filter and one blend filter, but since I can't see the textures, I also can't see if it is all good.
What's more, you have an unnamed and unedited animation present in the Sequence Manager, but if your model doesn't have animations, you should delete it.
The second thing, make sure when you import the textures to the map that you import both used textures (tex1.blp and tex3.blp, as far as I can remember) and they have the same import path as in the Texture Manager of Magos' Model Editor (tex1.blp and tex3.blp).
This is all, of course, if the model textures work in the editor in the first place, but, as I said, I can't see them because you didn't provide the textures for download in the attachment of your post.
