found a work around...if I add the the "FTP/HTTP download" to my favorite application, the whole feature will then work.
Looking closer at the links, it seems like the 2 different methods of loading the application directs you to 2 different links :
Method 1 : Via My Favorites (works)
https://your.ip.address/web/download_mgr/downloads_main.html
Method 2 : Via Applications (doesn't work)
https://your.ip.address/web/index.html?id=schedule_downloads
Can Dlink take a look into this?
