I have installed Courier on a development and production sites. The development site is local at - greatpowermedia.com.dev and a production site is hosted with the url as greatpowermedia.com. I also have a language support for spanish so the development site's content tree looks like this:

Content 

greatpowermedia.com.dev (en) - Supports English - Managed Hostnames domain: greatpowermedia.com.dev

greatpowermedia.com.dev (es) - Supports Spanish - Managed Hostnames domain: es.greatpowermedia.com.dev

The Production site  is a hosted site.

Content 

greatpowermedia.com (en) - Supports English - Managed Hostnames domain: greatpowermedia.com

I have requested the support staff at the hosted site to Edit Bindings for the site in IIS 7 to include the host name - es.greatpowermedia.com. which they have done.

Now I have attempted to transfer the contents from my development site for the spanish language to the hosted site and I get this error:

Also when I attempt to reach the site es.greatpowermedia.com I get this - Oops! Google Chrome could not find es.greatpowermedia.com

Please help. What am I missing?
