Can't view or download PDF from publication list or publication page

I have what seems like an obvious problem, but I can’t seem to figure it out. I’ve set up WP Publication Archive (thanks!!!) and have created a new page with the

[wp-publication-archive]

shortcode to produce a list of my publications. So far so good. And when I look at that list, I see entries like this:

The Title of My Publication
(January 8, 2015)
My-file’s-filename.pdf View | Download
Summary: This is a brief summary of the contents of my publication.

Also good (and very nicely formatted, I’d add).

The problem is with this line:

My-file’s-filename.pdf View | Download

Clicking on My-file’s-filename.pdf does nothing.
Clicking on View takes me to a full entry for that publication.
Clicking on Download takes me to a full entry for that publication.
None of these links allows me to download the PDF!!

This is also true on the publication page itself — that is, clicking on View or Download just takes me back to the publication page. I never get to the PDF.

Am I losing my mind? Missing something obvious?

Thanks!
