Has Cunjo gone out of business?

I’m having trouble using my Cunjo ID to access and use the Cunjo social media plug-in on my site. An e-mail sent to support@cunjo.com was returned as undeliverable and a visit to the http://www.cunjo.com web site revealed that although the home page is still up, there is nothing behind the scenes. Clicking on various pages just brings up 404 notifications and the like. Does anyone have any information on this?

The site I’m trying to use Cunjo on:

Thank you.
