title: NuGet isn't showing any packages
body: <p><img src="https://i.stack.imgur.com/rmiVz.png" alt="Empty NuGet Dialog">
  I've tried going to the URL listed for the official package source with my browser and I only get an empty list.  I also tried Phil Haack's source found while Binging this issue and got a similar empty list.</p>
  
  <p>It could be firewall related - I'm at work, now, and this worked just fine the other day when I started playing with NuGet at home.  But NuGet seems to be using my IE settings and I am able to access StackOverflow, as you can see.  :)</p>
  
  <p>Is there a way to download the packages to a local folder?  I would then add that folder to the list of sources for NuGet to check.</p>
  
  <p>Thanks!</p>

  <p>PCs are currently RIGHT next to each other - both on same wired network connected to same router, etc.!</p>
