Go to your plugins folder ( [your installation folder]/wp-content/plugins )
find the downloads-manager folder
in that folder, there is a file called functions.php
Edit it
find the string : <!–download table–>
and replace it with [download table]
save the file
upload the file back to your server
to make the download list appear in your post just use the
[download table] code instead ..
That should fix your problem ( it did for me )
