Technology is a bummer sometimes. I think what you've stumbled into is an
ebook that's protected by digital rights management (DRM). The way the
industry's implemented this protocol involves having an Adobe ID (but not
necessarily Digital Editions). If you have Digital Editions installed on
your PC, you should have obtained an Adobe ID as part of the registration
and installation process. Once registered, Adobe keeps track of the number
of times that your ID is activated, thinking that you're installing Digital
Editions on devices. The Aldiko app should recognize your Adobe ID in some
way - either it's asked you to enter the ID, or something like that, when
you registered the app. If all is well, then you should be able to use the
Aldiko app with no issues and download ebooks to your ereader (somehow),
then import them into Aldiko. I can't help you more, unfortunately,
because I don't have Aldiko to work with.
If you need to have your activation count reset, you'll have to contact
Adobe technical support and have them do it. A LOT of people have tried
this and gotten pushback from the techs on the phone. Be persistent: tech
support is the only function at Adobe that can reset the counter. Solve
the procedural issues first, so you don't have more frustration after the
reset....
