Endnote X8 crash when importing references from Pubmed or Scholar after OS X 10.12.5. update

Hi,

I updated my late 2016 MBP recently to 10.12.5 and since then Endnode X8 freezes when importing references downloaded either from Google scholar (.ris file) or Pubmed (.nbib file).

Thats very frustrating. Can anyone provide a fix for this?

Thank you,

felix
