Go Launcher - Lake Theme


Hi everyone, I'm new to this whole forum and android phones in general. I have an HTC desire. I installed this theme and the description in the market says it has 120 icons and 10 wallpaper options. When i try to change icons on my dock and select "theme's icons", no icons for this theme show up. Why is that? does anyone have this problem? can anyone help me? thanks in advance.
