Endnote Library back to progress from three months ago but up to date on online account


My Endnote library is saved on my onedrive that I share between my laptop and pc and recently there was an improper synch that has resulted in my library losing around 3 months of progress. Most attempts to resynch have failed to fix anything, however, when I log onto my online account it shows all my references that are up to date. Is there a way to download that as a new library and go from there or a way to resynch so that I don’t lose any progress?

Cheers in advance
