New Hikashop update breaking existing site

Hi,

I have been using hika shop for a while now and have just run into a problem.

I have installed the latest hikashop starter onto a clean joomla2.5 installation

www.curveaceous.com.au/hika/

I created an About Us page which was linkedto an article and it was working fine.

I installed the latest hikashop and created a product inside a category.

When i created a menu item linking it to the product, i get a database error.

Even the origionl about us page that was working fine is now broken with a database error and a reference to a hikashop product in the url?

thanks.
