I'm using the android app, Bluefire Reader which is using Adobe e-book DRM.
After I reset my android device several times, the app says that "Authorization Failed: The account you tried to log in with is activated on too many devices.
However, I used only one device.
Please fix this problem with counting devices and please let me know how I can activate it again.
Try Adobe Live Chat: http://www.adobe.com/support/chat/ivrchat.html
They can reset your authorizations, and then you must reauthorize any devices you still need.
(Unfortunately, Adobe haven’t got round to an admin website for viewing and editing authorizations.)
Some of the representatives haven't been properly trained and don't know what to do (and claim there is nothing they can do);
in that case the only way seems to be to give up that chat and try another session hoping for a properly trained representative.
If your problem is with another device using Overdrive, Bluefire, Aldiko or similar third party app, it is recommended not to mention that app when on the chat, just mention that you have run out of authorizations (E_ACT_TOO_MANY_ACTIVATIONS) . Thanks to AJP_Bear for that tip.
If it is Live Chat you have already tried and couldn't get through to, I'm afraid I'm not sure.
