How can I find my insert products?

Hello, I´m a Wordpress Beginner an I´m using DMS (Pagelines) and I´m using also WPMU Classifieds.
I added a product but I can´t find it. The same with Classiefieds Checkout and My Classifieds. If I click on my Website on these buttons there is nothing to see, they are empty. What do I wrong? Work Pagelines with WPMU ?

Thank you
Simone
