I think the only way is going to be to contact Adobe directly to see if they can help.
Good luck, and let us know how you get on with them.
Try Adobe Live Chat: http://www.adobe.com/support/chat/ivrchat.html,
or as a slight short cut try http://helpx.adobe.com/contact.html?product=digital-editions&topic=usi ng-my-product-or-service
Click on 'I still need help' and then you should see 'Chat with an Agent' at the bottom of the page.
'Ask our experts' will indeed just lead you back to this forum.
Sometimes you will get ‘Sorry! All agents are busy— please check back soon.’
Don’t refresh the page, just hang on and it should eventually go to ‘Chat Now, and agent is available’.
