Error getting licence

Hello,

I authorized Adobe Digital Editions using no ID but just through my computer. Then I added 2 e-books. Then I remembered I have an Adobe ID. So I removed the two e-books, unauthorized the application, authorized it again this time with my Adobe ID and tried to add the two e-books again. But it gave an error saying:

So I unauthorized the application again, trying to authorize through my computer (not my Adobe ID), thinking that this way maybe I could re-add the e-books. This did not work, so now I can't read my e-books and I just bought them today...

How can I set the license of these e-books to my Adobe account? I have the receipt of my purchase with today's data and everything. Please help me. I need these books for school.
