Problem with Google Gadget Controls

I was going through the steps in Google Gadget controls tutorial on http://ajax-softwareag.com/
The step for installing google gadget controls (Step 1: Install Designer CAF Google Controls) is failing in my case and is giving the following error:

Network connection problems encountered during search.
Unable to access “http://www.ajax-softwareag.com/sdk/updates/”.
Error parsing site stream. [The XML stream is not a valid default “site.xml” file. The root tag is not site.]
The XML stream is not a valid default “site.xml” file. The root tag is not site.

I am using Designer 7.1.1 as speicified in the tutorial. Did this work for anyone else?

thanks
