Checked all 3 browsers (Chrome, Firefox, and IE (11.0.15)), and made the changes you noted... Tried accessing mydlink.com using all browsers, and same result. The "Dlink Java application.." window pops up for a second, than disappears.. then it looks like its loading, but get the "loading" spinning hub, with the "retry" button under it...
should I try uninstalling mydlink from my PC and reinstalling?
