Setup Guide

Is there a setup guide for this plugin? I have downloaded and installed and then them used Filezilla to upload a file and using the short code placed onto a page on my site I can see the file but each time I try to down load it I am taken to the s2member signup page. It is like the plugin can’t see that I am the admin

I have also setup a test account giving the account level 4 access and I am still having the same problem.

Have I done something wrong in the setup?
