Boy that green on the home page is bright. You don't think you could tone it down a bit? My eyes are sore from looking at it in contrast to the bright magenta. While the product packaging is much more subdued.

Your buttons have no rollover states. I suspect when you imported your pages, you did not have your layers import set up to place (and I can never remember or make sense out of the options) items on layers on equivalent layers.

I have seen this happen often but my memory will not retain the correct option.

But if your buttons worked before, then now all button states are probably on the same layer.
