Hello

Just purchased Pro version for the grouped product functionality only. I experienced an issue.

• First when trying to Download All I zip a single file only not all of the files available for download
• When chose checkboxes + download all button
  • If I chose one checkbox only regardless which one it always downloads lates file, not the chosen one - as well it creates a zip archive on single (latest) file
  • if I chose all (two) checkboxes - it again downloads only latest one
• When I chose links + download all button - button downloads only latest file, when clicking a link I get an error 403  'The server understood the request but refuses to authorize it.'

to make it more fun even single downloads which worked perfectly with the free version now returns 403 error 'The server understood the request but refuses to authorize it.'

How I guess it supposed to work:

• When clicking download all - it zips all files into one archive and download starts.
• when marking single checkbox - it simply should start downloading (no zipping).

as well this 403 error is a huge issue

Hope you can help me.
