Virtual product not show !

What steps will reproduce the problem?
1. Go to my font-end at link : 
http://digital-everyday.com/digistore/index.php/sample-stationery.html
2. You can see "There are no products matching the selection."
3. That is my issue !

What is the expected output? What do you see instead?
- The virtual products are not showed in font-end, although i can see them in 
back-end via "Catalog > Manage Product". It look like the products stay at a 
wrong folder, not at "Sample Stationery" created.

What version of Magento/extension are you using?
- I use Magento-1.8.1.0
