Acrobat won't export/convert .pdf
I'm trying to convert a 10-page .pdf to a spreadsheet using the usual methods that have worked before-- File > Export To > Spreadsheet > Excel Worksheet or the same thing via Tools > Export PDF. It won't export to Word or XML either. What happens is that the progress boxes appear for a few seconds but a new file is not generated. Using the Tools method, the Save button is "blued out" so that it cannot be used.
It appears to be more like a permissions issue but there's no problem with the account. OSX 10.15.1, Acrobat DC 2020. (Licensed in the USA but using in Europe though I can't find an issue with doing that.)
Thanks for any suggestions
