Question
[error] e_adept_document_too_short
After downloading the EPUB of the 3 ebooks that I purchased in the Google Play Store, the ACSM-files don't open in ADOBE DIGITAL EDITIONS because "Communication problem with license-server : E_ADEPT_DOCUMENT_TOO_SHORT :".
Deleting the Adept key in the Registry Editor and reauthorizing ADE didn't solve the solution for me.
Waiting for an answer by Adobe.
