Link to the model download link on this site of the model you can not import.
None of our models are directly extracted from the MPQ all are custom made or atleast custom skinned.
If you notebook edited the model, then that ups the chance to 99% that it is damage or curropt as you have made changes to the model and thus the model is no longer assured to work.
If its just a skin, import it over the default skin WC3 uses for the villager.
If you want both skins available, use a program like war3modeleditor to change the skin path as it is easier and more reliable as it seldomly makes mistakes.
