E_LIC_ALREADY_FULFILLED_BY_ANOTHER_USER

I had a crash and had to reinstall my Digital Editions.  I have downloaded all my books from my kobo account, but editions will not accept them.

Looking on the website, it says to contact the book seller to ask them to reset the license.  So I contacted Kobo support and they have said they

have no control over the license.  So I deleted my authorization on Editions and to put it back it shows the ebook vendor and mine is Adobe ID.

So who do I have to contact to get the license reset?  I had one computer with the authorization and another without.
