OCart Product Excel Module

I have purchased the module Ocart Product Excel for importing products via excel spreadsheet.
After following all of the install instructions, I receive the following error when attempting to upload an excel file (based on their sample file) to Open Cart ...

Notice: Undefined variable: url in /home/www/shop.mysite.com/admin/controller/catalog/ocart_excel_upload.php on line 65Warning: Cannot modify header information - headers already sent by (output started at /home/www/shop.mysite.com/admin/index.php:83) in /home/www/shop.mysite.com/vqmod/vqcache/vq2-system_engine_controller.php on line 28Warning: Cannot modify header information - headers already sent by (output started at /home/www/shop.mysite.com/admin/index.php:83) in /home/www/shop.mysite.com/vqmod/vqcache/vq2-system_engine_controller.php on line 29

The line 65 in is ocart_excel_upload.php:
$this->redirect($this->url->link('catalog/ocart_excel', 'token=' . $this->session->data['token'] . $url, 'SSL'));

I have emailed their support at contact@opencartart.com a couple of times and have gotten no response... if anyone has any ideas how to resolve this issue, it would be greatly appreciated!
