Step 1. Go to the download page of the Zerg Lurker.
Step 2. Scroll down a tad, and you should see the names of the files in light-green.
Step 3. Take note of how they're displayed. if you see only the lightgreen names, it means they dont have a path. If you see something like Textures\NameOfTheLurkerSkin.blp, then its' path is Textures\.
Step 4. Go to import manager, and change all paths of the files to those displayed on the download page. Remember, if on the download page it only says the name in lightgreen, then simply remove 'War3mapImported\' from the imported file's name.
Step 5. Save your map. Close worldeditor. Open worldeditor. Open your map.
