Can't install Diamond Desktop Theme

I click the get new themes button and recieved a list of desktop themes. I selected the Diamond theme and clicked the install button but nothing seems to happen. When I downloaded it from their website and ran the install it said it installed but does not show up as an available theme to apply.
How do I get this theme to apply?
