My Dropbox account on my work Windows 10 laptop has stopped working.
this seems to be because it's stuck trying to sync a file that no longer exists:

It's been doing this for days.
Those 8 files are just blocked - they won't update, because I can't make Dropbox forget the non-existent file.
I've tried recreating the exact file name with a dummy file to see if that unblocks it. I've done all the restoring links/permissions stuff. This is driving me nuts. Any help appreciated.
