I am trying to save my Numbers spreadsheet and this message (as stated in the question) is showing. I am also trying to export the file as a PDF and this message pops up -
The document “Social Stats record Spreadsheet.numbers” could not be autosaved. The file doesn’t exist.
I think this has something to do with me saving the file to dropbox as well as in my documents and the mac has got confused? I really don't want to lose my work as I've just updated it with a lot of info, how can I save the file and export it as a PDF without losing anything?
