my downloads are not protected

Hi,

I have downloads that I want only members to download. I created a download group that only members have access to. I uploaded a file via the media manager and checked the group from the drop down. I inserted this file into a page. However, I am able to access the download when logged out of my site (a visitor).

I double checked over and over again to make sure my setting are correct...correct permissions for visitors and members.

Any ideas on what the problem could be?
