you can't link directly to the document. The free server will not allow a direct link to the pdf file. SO you have to go to the html page and once that is open the pdf file will open by clicking the link. So anyone that links directly to the document won't always get it. If you open the page and then click on the document link you will.
Hope that explains it. It is all the free webserver situation.
