Cannot open pdf in EndNote X9

So recently when I try to open an attached pdf in EndNote it instead opens a window that simply displays the reference details (see figure attached).  I can then scroll down in this window and open the pdf link, but that’s a pain to do and I don’t think EN will save any of the changes I make.

I tried the workaround by downloading foxit reader, and that is now my default reader, but it didn’t help.  Adobe is up to date.

Using Windows

Any help would be appreciated.

How are you trying to open it?  I usually right click on the PDF preview tab (circled in the attached image) and choose “open in Adobe Acrobat”.
