Fatal error for Spiral Scripts: Spiral Paid Download Plugin for Virtuemart

Hello. I bought Spiral Download plugin for Virtuemart.

Order Number 4DSW03479
Order Date 2017-03-04
Order Status Confirmed

Joomla 3.6.5, Virtuemart 3.0.18, Dropbox, PHP 5.4.3.

When I click on the download link, I get the error:

Notice: Undefined variable: app in /administrator/components/com_amazons3/helpers/order.php on line 84
Fatal error: Call to a member function redirect() on a non-object in /administrator/components/com_amazons3/helpers/order.php on line 84

Please, help.

P.S. I have sent you more information and login/password to access the site on email.

Hello, my apologies for this, it is a coding error in the AS3 Manager extension, we will make a new release today so that you can get the download working.

Nothing wrong. Thank you. I'll wait for the update.
