Well if you click on the PDF icon, you should be able to download the files – it works for me. The used "PDF portfolio" format is sadly a bit special. Recent Adobe Reader versions can open it, but under Linux I had problems. I found PDF Studio Viewer (not FOSS, but at least free) which can open and render the files.

(Beats me why they didn't simply concatenate the PDF files forming a submission into one regular PDF file; that would have been simpler and more convenient for everyone.)
