Zend_Exception: No object named "request" is registered.

Exception is being raised on mc.Subscribe call. Worked yesterday so must be API change my code

        MailChimpManager mc = new MailChimpManager("api-key");

        EmailParameter email = new EmailParameter()
        {
            Email = model.UserName
        };

        EmailParameter results = mc.Subscribe("listid", email);

Solved. It was obviously on the api side. here is a response I received from mailchimp support. no longer receiving the errors.

Hi Tim, Thanks for reaching out. Earlier today we were seeing an issue with the list/subscribe call returning a "Zend Exception" error when the double_optin parameter was set to true. Our developers have pushed a fix for this and at this time list/subscribe calls are coming through as expected. We apologize for any inconvenience this may have caused. If you have any additional questions or if you continue to experience any issues let us know and we'll be happy to help.

Thank you, Reeve
