Thanks mandsconsulting for your quick help!
The url specified in Download Monitor is
/homepages/13/d332028505/htdocs/content/xyz.zip
This configuration works fine when using the download monitor link (https://mysite.com/wp-content/plugins/download-monitor/download.php?id=12)
but the the links Email Before Download returns of the same file do not work
this is the link EBD returns with “Hide/Mask Real Url” on (does not work)
https://mysite.com/wp-content/plugins/email-before-download/download.php?dl=199a5fd1dd67dfa47214d42388210b2d
and this is the link EBD returns when I try it with “Hide/Mask Real Url” off (does not work for obvious reasons)

Any further help you have is much appreciated.
