CSS - Fix Links in Web Template - Easy

I have a web template that I downloaded and noticed that some of the links do not correctly for whatever reason. They are the main links "Home" and "Portfolio" on the main [login to view URL] page. Test it and you will see what I am talking about. I think it's something with the css file, not sure what and I don't have time to figure it out. An experienced CSS programmer should be able to figure this out fast within a few hours I would guess or maybe sooner. Easy project for the right worker. I need it today if possible.
