Removing category meta from single product view

Hi

I have used Marketpress for a website I've created, http://www.heapssausages.com. Its a genesis powered site running the Landscape theme.

I'd like to remove the category info from the product view and have attached a screenshot of what I mean.

To do this so far I spoke to the theme creators and they suggested adding the following to the 'functions.php' theme file, specifically adding;

//** Remove the post meta function */
remove_action( 'genesis_after_post_content', 'genesis_post_meta' );

This hasn't worked and I suspect this is because its the store's post meta which needs listing. Can you guys help please?

Thanks

James.
