The error Adobe device activations reached may occur in a SimplyE app (especially on Android devices) when opening the SimplyE app on a mobile phone or tablet. The error indicates that a particular "user" account in the Circulation Manager has been activated on too many devices or too many times on the same device. This is an error resulting from Adobe's DRM licensing scheme. (For more information on how Adobe DRM works, see the article How Adobe DRM Works in SimplyE.) In the case of SimplyE, the "user" is known in the Circulation Manager by a unique identifier, which the Circulation Manager uses when communicating with an Adobe licensing server. Adobe allows each user to "activate" a total of six devices to access DRM-protected content. The max activations reached error occurs most often when a user uninstalls the SimplyE app from a mobile device without logging out of the library accounts she has created to library collection(s) in SimplyE. Users sometimes uninstall and reinstall the app as a potential way to resolve app issues. But doing so without first logging out of the library account(s) burns a device activation each time.
