download csv of people

G’day Andy,
First, thanks for your work on this plugin – it’s generally brilliant!!

Now (and I guess it’s just me ‘cos I’m not seeing other questions about it) – I can’t work out how to download my complete directory, or any subset of it for that matter.
When I click the [Download] button, the site just goes off to a blank page and sits there (apparently forever, although I generally give up after a couple of minutes and hit the “Back” button)

Would really appreciate your guidance.
Thanks healps
