Theme loading and expressing issue

I have uploaded a new theme to my blog that I created on Artisteer. When I viewed it, the footer was up in the primary widget area. As I had modified the footer area to contain several links and some text, I removed that information in Artisteer and loaded a new theme. Although I’ve activated the new theme, the old theme is still showing.

So 2 questions – why is the footer showing up at the top of the sidebar area, and secondly, why won’t the second theme show when activated?

Thanks in advance,
Barb
