I'm not sure what you mean by changing the site from HTML to DIV, since <div> is an HTML tag, although I assume you mean you went for a tableless design and started using more CSS, minimizing the amount of HTML on the site. If so, I can't understand why that would translate into Google not liking you more.
In checking out your site, I can tell you that a HUGE RED FLAG are the many many links on the homepage which just scream SEO spam. Never ever do that. If you used to do it, it's possible that the massive changes to the HTML code caused Google to take a deeper look at your site, and that set off a flag that it never paid much attention to before.
Also, if you had read the forum rules, you would have known that posting a link to your site isn't permitted in this forum. That's why there were 10 notices all over the place to read our rules.

Thanks so much for quick reply. I've searched the net for many forums and liked the open diallogue of yours. Read much from your technical subscribers and figured that a live case might wet their appetite to make use of the theory.
In answer to your notion that Google have taken a deeper look I can tell you factually that their is no spam on my site at all. I do have the best offering in the UK and every link on my site, every word, every text paragraph and image is only related to products I offer in exact words that match the product. For your technical people I think my case is a real challenge. Why did my site dominate the searches for so long (correctly if you assume that I am the best on the net for my tiny niche) but reject when converted to a better/slicker code. For your web designers I think this is a subject worth understanding.
Very sorry if I've infringed the rules but I reckon that all the forums deal with technical theory only so perhaps a real end user with a problem might spark a real debate about the actual results of the theory so entheusiastically discussed. I could have disguised the questions as third party or general thread but figured you were up to the head on dealing with the reality.
Yes, I'm just a low key antique furniture dealer but I'm truly trying to master a subject that very few of my breed will even contemplate.
Beat me up as much is needed but please first understand that I am genuine and am (just about) smart enough to make your forum hit some rational diversity that perhaps before might have been parked up as solved without checks.
Keep me in play and I'll test the bounds of the forums capability.
Hopeful
