EPUB downloaded without ID

Hi,

I bought EPUB 2 years ago and downloaded it without Adobe ID. The machine I did it on is now gone. I created and Adobe ID bought new books and downloaded them perfectly fine. Now I wanted  my old books but when downloading them I get E_LIC_ALREADY FULFILLED BY ANOTHER USER ERROR. Bookstore did change the token for me but it did not help. Same error. How can I get old books back to the new ID?

Thanks!
