Just an FYI - if you open a new question you're more likely to get a response. Not that we mind so much, but I only saw this question because I received an email since I'd already replied to the thread. No worries, just an FYI
Anyhow... just taking a quick look here...
I ran a site: search in Bing, and it appears your home page is not in the index.
It IS in Google's index, but ranks 3rd when I do a site: search.
The short of it is, something is causing both Bing and Google to devalue the index page.
This could be for a variety of reasons, but I suggest you perhaps check out the new Bing webmaster tools as well as check for any errors/warnings in Google webmaster tools.
A quick look and I don't see anything - but when I get more time to check it out, I'll take a better look.
