I authorized my computer without an ID, then I downloaded my newly bought ebooks and fulfilled them on ADE. I do have an Adobe ID but I did no bother signing in. Moments later, I logged in to ADE with my ID to open old files. Now I logged out and revert to authorizing my computer w/o an ID so I can open my newly bought ebooks which I fulfilled on ADE without an ID. But the problem is I could not open them anymore. What to do? Please help. Hopefully I make sense.
