Importing references crashes EndNote x7 after update

Dear all, 

I hope you can help!

Since the update endnote, unfortunately, has started crashing.  I have been trying to import a set of PDF files to the a new endnote reference library with no success.

The program just crashes.  I have tried re-installing and using a different library but it still is not working. 

I’m currently a Windows 10 user, Endnote X7.7 

Any help would be appreciated
