Can't edit Theme Options (Possible installation error)

Hi,
I am trying to edit my theme options. I can edit the "Slide 1" options. But when I click on Slide two, Slide three, Slide four, Content One, Content Two, Content Three, or Branding the page doesn't load a new looking one. Yet the URL does change. I basically have nothing set up, therefore nothing to lose if we need to start from scratch.
Thanks,
Geoff
