Where has the add to cart button gone?

Hello guys, hope you can help me out fast. I just installed the latest version of Premiumpress responsive shop to my domain. I add products but the only place the add to cart option appears seems to be in grid view when you mouse over a product. It’s not there in list view and its not there on the product page. Can someone please tell me how to get an add to cart button on my product page. I’ve waisted two hours allready trying to find it myself.
