current version specify api key value

[xeux]

I installed and configured the bundle, then did I campaign create using the API and it showed up in mailchimp.com, but few hours later, I did it again and return code -100 specify apikey value.

Update, using acutes in "subject" and "from_name", also when in html I use a twig template and non one line html it breaks with this error.

Break example:

    $data = $mc->getCampaign()->create('regular', array(
        'list_id' => '123456',
        'subject' => 'Envío',
        'from_email' => 'info@realestate.com.pa',
        'from_name' => 'Bienes Raíces',
        'to_name' => 'fans'
    ), array(
        'html' => $this->getContainer()->get('templating')->render(
            'DemoBundle:Mail:email.html.twig',
            array('propiedades' => $propiedades)
        ),
        'sections' => array(),
        'text' => 'test',
        'url' => 'http://www.example.com',
        'archive' => 'test'
    ));

Update 2: html field works with multiple lines text, but breaks when using acutes and special chars or symbols, for example the special char of copyright ©, instead you should use the html version & copy ;
