I just upgraded to x9 and have noticed many, many bugs!!! Arghhh ...
The most recent one and the most time consuming to correct is when a new reference is added to the library. I have to correct the Journal Name in the record. The field is misplaced in every single case! When the record is initially added, the journal name is "appended" to the last author name in the author field. To correct the entry, I have to manually type the journal name in the journal field and delete the journal name text from the author field.
You can replace the current EndNote Import filter with the one from our website.
Double-click on the downloaded file to open it.
Click the File menu in EndNote and select Save As.
Be sure to save it with same name then Click Save then Close the window.
You can now delete the file that was downloaded a copy has been added to EndNote.
You can now try to import references into the library again.
