Products: Reset number of possible downloads fails

If I click on the left waste bin* when I am editing a single product, I get the error:

Fatal error: Call to a member function setQuery() on a non-object in C:\xampp\htdocs\joomla\administrator\components\com_hikashop\classes\file.php on line 166

* see:

Please change the code:
$this->db->setQuery($query);
return $this->query();

by the code:
$this->database->setQuery($query);
return $this->database->query();

in the file administrator\components\com_hikashop\classes\file.php and that will fix the problem.

Thank you!

Indeed this fixes the problem. Will this be fixed in the next Hikashop release?

Yes it will.
