I am having this same issue!
Adobe intentionally broke the site by removing the option to directly download the .ase file. If you have CC there is some way to open the palette from CC library. I have CC at home but I'm using CS at work so I'm SOL. Easy enough to just create five new colors in the swatches panel in Illustrator and type in the HSB values, though.
I'm a CC subscriber, so I just need to create an Adobe Kuler color theme, then my theme will be available directly in the CC library.
