[Plugin: YAK for WordPress] Export data for Orders not working

The Orders page is mostly working as expected, but the “Export data” link does nothing. No errors, no response, no data downloaded. Please advise.

I assume that the Export Data option, when working, will give me some kind of useful way to see who has purchased a certain download so that I can notify them of updates, etc.–like you did when your YAK Handbook 2.1 came out and I received email with a new download link. If not, how did you do that? I don’t see anything about that sort of thing in the handbook. Thanks!
