Fatal error: Class 'VmConfig' not found ?? after paying with iDeal

[Felipez85]

I'm recieving a fatal error when I'm done paying in iDeal, it should redirect me to the Success / Thank you page, but I recieve this fatal error:

"ideal Fatal error: Class 'VmConfig' not found in com_virtuemart/helpers/cart.php on line 74"
(with this url: index.php?option=com_ccidealplatform&view=ccideal&layout=checkout.ccideal_post_basic_result&url=urlSuccess&orderID=17d5035&extn=virtuemart&amount=51.9)

I am using Joomla! 2.5.24, Virtuemart 2.6.6 (recently upgraded from 2.x), CCiDeal 4.1.2, ING Basic account

This is standing on line 74 in cart.php (I have SSL turned off in config):
var $useSSL = 1;
    //     static $first = true;

    private function __construct() {
        $this->useSSL = VmConfig::get('useSSL',0);
        $this->useXHTML = false;
    }

Hope anybody has an idea..? would really help us! Thanks
