Models don't work: the magnificent green cube

[missfortune1]

Sorry for my English is horrible, first of I must say that I'm a retard everytime i download something That Is not official in every game it not work properly. I can't specify the model beacause all the models i downloaded do the same thing (about 40) I tried to delete the war3mapimported, and tried to save and reload the map, i have followed the tutorial but it still not work.
What can i do?

Well I guess it coulf be the skins on a certin model if it is a custom skin then if would show up as a green cube in the editor and only its shadow will be visble in-game, if this work and if you havent tried that before congratz I hope you all of luck

in that case what should i do?
(yes i tried even to close and rerun the editor)
now the models that have only the mdx file work well, but what i should do with the others that have even the file.blp ? i have to put it where?
