Rich snippets working?

Dear Lester Chan,

first of all: Thanks for your awesome Plugin and threa great support you give here! This really comes from my heart 🙂

I installed your Plugin on my Website, I use it for my default page, not an blogentry.

But there are no Stars on my google Searchresult. I activated rich snippets in the plugin options.

I ran my site http://www.klartraumhandbuch.de through the validator (https://developers.google.com/structured-data/testing-tool/) but I’m not sure what to make of it.

Could someone tell me if it’s just takes some time for google (3 weeks now) or if there are any errors on my behalf 🙂
