min receivefile size error

Trying to set up back up from an Acer Desktop running Win 7 to Duo V2 running 5.3.7,

1) I set up the source OK, the Test Connection works.
2) I set up the destination folder OK, but the test option is not offered to me.

Set up the back-up job and 'apply'. Then 'Run' and seconds later I get a completed notification.

However, when I look in the destination folder - nothing there!

I click 'Show' and get this message

I saw the other entries on this topic and they said it would be fixed in version 5.3.7 - well that is the version I am running.

What is happening?
