Sopho pretty much covered it well but anotehr thing... Make sure that you have the file imported in with your import/export manager in world edit and make sure you've changed the paths to those that are correct. It's a more basic problem but people who are relatively new can not know that... Also if you ahve made any icons, make sure that they have been (after importing) selected in the unit editor manualy by selecting the import bubble in the 'game interface' section and then selecting the icon (if there are multiple oens). This probalby wasn't of any help but, I like to think I've helped someone. Heh...
