: I have a DELL Axim x30, that I have been using to read ebooks for years. I have Adobe reader for pocket pc installed on my device. I have been having problems with trying to load ePUB ebooks and PDF ebooks onto my device. I downloaded the latest version of Digital Editions, and validated my desktop computer. When I open Digital Editions up, it does not seem to recognize my DELL as a reading device, thus I cannot transfer the ebooks to my device. I looked at a couple of recommendations by other users to people with a similar problem to mine, but nothing seems to work. I put the books directly on my flashcard and then tried to open them up with my Adobe Reader for pocket pc. I either get an unsupported file format or file appears to be corrupted error message. Help, I do not want to have to purchase an eBook reader when my pocket pc has been working so well for all of these years.
