Backups...
Devise a system of backups so you can revert to an older version of your document should something 'bad' happen to your working document.
Removing Coding...
You may need to remove the EndNote Basic coding in the background of the Word document in order to make final edits or prior to submission of your manuscript for publication.
To do this in Windows, click on Convert Citations and Bibliography -- to Plain Text.
To do this on Macs, click on the Remove Field Codes command.
REMEMBER: create a BACKUP. Once you remove the field codes, EndNote Basic will not be able to work with the document to manipulate the citation information.
