I am trying to open a .acsm file in Adobe Digital Editions 2.0.67532
I keep getting the error E_ADEPT_DOCUMENT_TYPE_UNKNOWN
I have searched the forum and found this question asked previosuly - but NOT answered.
I would like to know what this means and why I can't download my book.
Very frustrating to try and access customer support from adobe to be thrown over to a forum which has the same questions I seek the answer to posted MONTHS ago - and they are still unanswered. There has to be an easier way!
