EndNote X7.2 for Mac PDF Attachment Error

My research assistant sent me a library with about a dozen PDF attachements.  When I try to look at the attachments, I get this error: “This URL (/Users/ … .Data/PDF/0084353895/Brown-2013-Case formulation in personality dis.pdf) could not be launched.

I saw there was a similar question in the archives about three years ago with X4, but the answers were almost exclusively for PC not Mac and the one Mac answer was not hellpful at all.

All the references appear to have file attachments, I’m just trying to figure out how to access them.

Thanks!

How did she send you the library?  as a compressed .enlx file?  or just .enl file (which doesn’t contain the pdfs).
