Can't get it to resolve correctly

Hi there. I'm stumped.
Wordpress 3.04 Multi Domain: 1.1.3

I think I have everything set up as needed, but the one issue I could have is that psek doesn't offer dedicated IP addresses so I'm not sure if that's effecting things.

The multi Domain plug in is not detecting any errors (it was at first) and I believe all the A name, parking is correct, but when I try to use one of my sub domains with the new tld, I'm sent to the "create a new blog page" and not to the correct blog.

Here's the sub domain that works:
http://demo1.digitalpto.com/

Here is one that doesn't resolve correctly:
http://demo1.digitalpta.com/

Psek is saying I have to ask the developer as they don't know of any special settings.

Thanks so much in advance for your help!
