Pagelines DMS limitations?

I just wanted to know some of the limitations of the pagelines DMS basic version before using it. Well I was starting to use this DMS however got stuck at the nav elements coz I can’t seem to have more than 6 nav elements. Its like the pages are created but not seen in the nav section of the DMS. I switched the theme to default themes like the “twenty eleven” and the nav section is fine(displays all the nav elements). Is this a limitation of the basic version of pagelines DMS coz there are 8 nav elements that I need to put in the navbar? Can I know the other things that I cannot do with this version?
