Help! "PDF Filter" error message


When trying to import a PDF into Endnote X8, I get an error message saying " The required filter, “PDF” is missing. Please move it to the Filter Folder and try again". 

This function was working fine a few days again. I haven’t installed any new updates for Endnote or my OS. 

I re-downloaded the Endnote Filters available online, and restarted the program, but no change. 

Any help is much appreciated!


re-downloaded and “saved as” with a new or old name?
