I am encountering the issue of Connection error detected. Whenever I use Adobe Digital Editions to open acsm files, the message appears and I cannot get access to the Ebooks. I have tried all the methods that were suggested from the forum but none of them worked. I have tried V3.0 V2.01 V4.5.10. I have tried to re-authorize my account. I have tried to reset my IE settings. I have tried to re-download the acsm files. Nothing worked! So frustrating! Can anyone help me get out of this?
