Importing Endnote X library into Endnote Ver. 9?

My writer has Endnote X and I have Endnote 9. She created a library which I want to import into my current library. My first attempt to open the library directly, resulted in an error message stating I was unauthorized to perform the function.  Next I tried to import the library into one I created.  No references were imported.  I tried once again to open the library directly and it did open this time, but it showed “0” references.

I’m thinking this is a compatibility issue because I’ve got the older version of Endnote.  Is there any way around this?  What can I do?  Thank you for any help.

The .ENL and .DATA file are in the same location.  I will check the permission status and then if it doesn’t work I’ll check with the writer regarding “compression” of files.  Will get back to you.  Thanks for the direction.

Thanks.  I deleted all versions and am going back to initial version emailed from writer.

Just a follow-up.  I unzipped the writer’s Data file and saved it prior to moving the .Enl file to the same location.  Once complete, I tried to open the .Enl file; it opened Endnote and brought up the references.  Perfect.

Thank you very much for your help!
