importing Model problem (help)

[joshua9406]

Hello I'm new here and to WE, The problem is that I've downloaded

a Model and tryed to use it, and I have read the Tutorial and after the importing I reopened the WE after saving then I attached the Model to my desired unit at first the green checkered box showed so I reopened WE again but it still shows up as a green box and there's a little message at the left bottom of the WE saying {War3Imported(name of the model).mdl} So I just went ingame but the model shows up invisible help....

Edit: P.S I have no trouble with models that don't have .blp folders I must be doing something wrong.
