OK. First thing, did you rename the file (just take away warcraft3imported// (for mdx only other wise known as models))? Second, did you actually test the map? Sometimes WE wont recognize the path automatically. If you didn't see it in game than thats okay. Try saving and comming back. If it still isn't working you got yourself a broken model, try a different one, or if your a modeler you can try and fix it!
