I was able to join 2 Adobe IDs and have them both authorized on my computer. All of my books now appear in ADE. I can open older books associated with my older ID, but I can not open newer books associated with my newer ID. When I try to open one, ADE asks me to authorize the computer for the ID associated with the book, even though it is showing as already authorized. When I proceed with the authorization, I get the message that this item is associated with a different ID. Somehow ADE no longer recognizes my new ID as being associated with my new books. I have erased authorizations, trashed the activation.dat file and reinstalled a fresh version of ADE, with no effect. Does anyone have any other ideas on how I can repair the association between my ID and my books? Thanks.
