travelling library

My student has a paper that she has written in Word, using EndNote X.  I have EndNote 9.  Everytime I edit the paper, EndNote replaces her references with ones from my library.  A travelling library would do the trick to prevent this I think, but when I try to export her library from her paper to a travelling library, EndNote 9 states that “the files is already opened and cannot be opened again”.  I then get a message telling me that the export failed. 

Am I doing something wrong, or is the a version issue?

Here are the instructions that I used, followed to the letter with a new library.

 

Open the document in Word.

  1. From the Tools menu, go to the EndNote submenu and choose Export Traveling Library.

2.  On On the Export Traveling Library dialog, select either:

  1. An existing EndNote library:
    Select a library from the drop-down list of available libraries, or click Browse to locate a library.

  2. A new EndNote library:
    You will be prompted to name and Save the new library.

Thanks, but I am not entirely sure I understand.  The library in the paper has been formatted.  But if I use track changes in Word, despite the fact it is formatted, the Cite as you Write function replaces her references with ones from my library.  I have tried to turn the CAYW function off, with no luck.
