Hey everyone! I’m practically very new to Endnote; I am currently writing my doctorate thesis, but I managed to mess it up somehow. I think I turned a setting on; now every single time I add a citation; it takes 1-2 minutes then it says “updating in text citations” and a bunch of paragraphs start to show up and my citations are gone. Please help 
Oh no! We hate when the citations go away. I’ve been using Endnote since my own diss…about 30 years ago, and this is still a problem now and then. The bottom line seems to be DON”T try to use the cloud for your documents; make sure the endnotes file and the document is on the same hard-drive (ideally) although an external drive/stick is fine. Especially, don’t get into that OneDrive environment. Meantime, the Endnotes help desk can usually help you recover text fields if you have a critical document that’s gone bad, but it’s better to prevent the mess in the first place.
I would also recommend turning OFF the “cite as you write” feature. (I’d guess this is the setting you turned on.) That creates a lot of havoc even when staying on a single ‘puter and adds nothing of value until you’re in the very final stages of editing a document for publication.
