What an astonishing mess. I have activated my account, but ADE won't open a pdf file. What I get is a bunch of meaningless numbers that tell me the user absolutely nothing. And when I get to the forum I just see hundreds of messages about various and sundry things and none of which solves my problem. I would like to have Adobe Digital Editions working on my computer, but I don't need it. If Adobe wants to keep people around, they should give meaningful error messages and make it a lot easier to get help. I'll just use another ereader.
