Static page as home page

Hello, we have bought the WP Theme “Magazine Pro” a month ago. We are happy with your theme, but we would be pleased, if you could help us on a little problem.
We want to use a static page as home page (front-page) with custom content, but If we change in >WP Settings >Reading >Your homepage displays >Homepage to >A static page (to our custom homepage), the theme still displays the content from the theme front-page.
We are relatively new in WP, so our question is, can we add – without any risc – a code snippet in your theme to display our custom homepage (frontpage) as static page? Can you help us with a code snippet and where do we have to add it?
Thank you for your help.
