I have 2 ebooks from Entitle that I retrieved from my phone that recently died. Entitle's website went down shortly after they shuttered their business, so I can't log in to read the books on the Entitle app. Or in ADE, since I don't remember my Entitle password (I had saved it in the Entitle app on the old phone) and I'm not sure that old password would work in ADE anyhow since Entitle's site is down.
Were you ever able to get this resolved? I have the same issue now. I have all my books downloaded, but can't access them.
