Interesting. I have no problem watching my old Slingbox Classic using that software. I take it you can watch it on the web-browser ?
Actually, although Sling will not admit it, you can watch the Classic on their new M1 Desktop Player. Unfortunately they have hidden it again. The only link I can find is http://www.sling.com/Products/SlingplayerApps and that doesn't work. And going through Products > Slingplayer doesn't help me as I am in the UK so they don't provide a link.
Moderators: Where have you put the player now ?
