HELP. Artisteer, Hikashop and CSS

Maybe I've already asked - I've lost track where I've posted. Can anyone tell me how to get an artisteer 3.1 menu to work with Hikashop? Module class suffix half works: the mouseover changes color on the vertical menu. However, for some reason the main button color on the vertical menu isn't loading. I've tried Inspect Element / Firebug and found nothing anywhere to explain what the conflict is. It seems to be taking the standard link color instead of the menu color.

It should be white/light background, rounded corners (from the image file) with no text decoration and a green background on mouseover also with no text decoration.

Apparently the green Vmenu png is loading but the there should be (I think) 3 Vmenu blocks loading for the white with borders that aren't.

I've also posted in artisteer forums so I know this version should be compatible with Joomla 2.5 and Hikashop.

Here is the Site.

Therein lay the problem. I've done what it says to do: but it's not entirely working. Something MUST be overwriting part of the css. But I can't find it!

The attachment shows how it SHOULD look. Mouse over is green (that part works fine)
