[Plugin: WP-eCommerce] No downloadable items with subscription

I’m using the WP e-Commerce plugin (3.8.13.3) with the Members Only (‘Membership & Subscription plugin for WP e-Commerce’) plugin (version 2.9).

I’ve set up a subscription (as a product) and have added a product download. Normally, the buyers are shown links to any ‘downloadables’ once payment has been made on Paypal. However, for some reason the Members Only plugin adds this text to the ‘transactions results’ page:

Thank you, your purchase is pending. You will be sent an email once the order clears.

This message is pulled from purchase-log-notification.class.php in /wp-content/plugins/wp-e-commerce/wpsc-includes and suggests that the plugin thinks the payment still needs to be cleared – even after Paypal has already confirmed it has cleared.

Weirdly, the plugin then continues to print the standard confirmation message for the ‘transactions results’ page (the message defined in the dashboard under Settings, Store, Admin). This shouldn’t happen as the error message (“your payment hasn’t been cleared yet”) will normally contradict the standard confirmation message (“thank you for your payment!”).

Worse, because the plugin thinks no payment has been made it also prevents the link to the ‘downloadable’ from being displayed. The link to the download does appear in the confirmation e-mail the buyer gets as soon as the payment has been made. This suggests that the plugin wrongly assumes that no payment has been made. If Paypal has already confirmed the payment has been made and if a confirmation e-mail has already been sent to the buyer than surely the plugin should know that the payment has already cleared?
