Hi,
I am having the same problem with unmatching record numbers across two different desktops.
Was the solution: ‘cancel syncing on both libraries, create a new version on one of the computers, sync it to the other - so we have two identical libraries - and then use this new version’ and then being careful to ensure syncing occurs correctly at the end of each Endnote session? Or did you find an alternative solution?
Thanks in advance.
