I’ve loaded the theme and it doesn’t look like the demo?

This is probably the most common issue. When you first load the theme, only your blog roll will show. You have to build the homepage widgets with your information to get the homepage look. The widgets can be found at Appearance > Widgets. Or you can choose to import the demo content and have it look just like the demo. It is really important to follow your themes setup guide and the steps that go along with it.
