Hello, I am having a similar problem, I am using a MACBOOK PRO and am unable to activate the Adobe Digital Editions. I have tried changing the name of my MACBOOK to no avail.
The Disaster Recovery Handbook : A Step-by-step Plan to Ensure Business Continuity and Protect Vital Operations, Facilities, and Assets:
Adobe DRM Error

Contact customer support.

Please help any adice or guidance that you can provide will be greatly appreciated.
I think your error is different than the known issue described in
"Error: "Failed to load XML.Whitespace is not allowed at this location" in Adobe Digital Editions 1.5 or later (Mac OS X)"
Notice that in your case the error message is different. The server code is different too.
Please open a support web case and we'll get somebody to investigate. Also, it might be helpful to know if this happens to just this book, or to all ebooks in your copy of Digital Editions.
