My EndNote 21 brings “object deleted” and has disorganised 100 references and removed some of them" I have 400 references.
I see you found the old thread on this topic. Have you tried to clean up the field codes? ( you need access to a library containing all the records to get this to work. You can also try exporting the endnote cited records to a new library first before unformating, just in case a collaborator inserted some of them.
Thanks Leanne,
Let me explore and see whether it will work.
