[Plugin:WP-e-Commerce] Upgrade to WP 2.8.6 and “Products” disappears.

Hi all,

I have updated to WordPress 2.8.6 (running Fusion theme). upgrade went fine, no major errors noted, however my WP-e-commerce plugin no longer appears to be accessible. I cannot see the “Products” listings on my Admin Dashboard and my Products are not showing up on my page (https://www.birminghamphoenixclub.com/events/club-events).

Within Plugins it doesn’t show up in the active, installed, or inactive listings.

However, the “WP E-Commerce Dashboard” plugin shows my revenue, sales and order requests.

And, if I attempt to reinstall the plugin it says, “Destination folder already exists. /…../html/wp-content/plugins/wp-e-commerce/
Plugin Install Failed.”.

Any help will be greatly appreciated.

Thanks
