I'm having the same problem. When I click on the 'Download Manager' link, it takes me to a page with nothing but manuals :( I've already successfully installed the e-license, but I can't get my damn instruments because I can't find an install of the download manager. :(
Edit: I've registered my dongle, and it shows that the Recorders is registered to my account. I can even download the file that is supposed to fire up download manager. But I can't find and install for download manager :(
