Rock tune page link and creation

Hello to everybody I downloaded and installed the free version of rock tune. I tried to link simple pages from the menu (head) but it doesn't work, even though the link is correct. Whatever page I click in the menu, the same screen always appears. Does this happen because I have the free version? Or what is the procedure? I created the home page, and everything is ok there, but I can't work with the links in any way.
