Create an Adobe ID link in ADE: page is not available

One of our customers reported a possible bug today: when she tried to create an Adobe ID directly from Adobe Digital Editions (ADE), it failed. Please see below for details, and advise and / or fix ASAP.

1. In ADE 3.0, she clicked on “Create an Adobe ID” link, which points to www.adobe.com/go/digital-editions-createID

2. The link above redirected her to another page: “Create Adobe ID”

3. Clicking on “Create” button redirected her to a page that is not available. As far as we can tell, no Adobe ID was created for her; it just ended in failure:

4. We tried to create new Adobe IDs using these steps and experienced this same problem.
