Sometimes, when I right click npm and select "Manage npm Modules", the package manages says "Loading published package list", but it comes back empty. See screenshot here: 
I am still able to install packages using the npm command, but they are not added to packages.json and I have to call npm init manually.
Comments: I have the same problem that Johngom. I had the VS 2013 update 2. Then, i updated to update 3 and the problem still ocurring. (Sorry for my english. I'm brazilian hihihihi) My packagecahce exists but my "Install Packages Windows" still empty everytime. I don't know what to do! Help me
