I’ve updated the documentation and included the missing SQL file to create the wp_wpsc_favourites table that stores the individual wishlist items that powers Add to Wishlist.

Please re-download Add to Wishlist from the original purchase e-mail that was sent to you. Shortly I’ll be making member facilities to allow customers to log in, manage their downloads/purchases and get priority support within the WP e-Commerce forum for Visser Labs addons.
