Wp e-commerce featured image not showing in "add new product page"

Hi
I wanted to use woocommerce, but from an earlier thread I understand the Videocraft theme is not compatible with it. You said is compatible with WP-ecommerce plugin. I installed and tried to use this plugin but when I try to add a new product, the featured image doesn't show up to enable me add the image. Can you advice me on what to do. This is urgent please. Thanks

 

Hello !

Please Go to
Appearance=>Editor=>Functions.php
