and Im greeted by " Error getting license, License Server Communication Problem: E_LIC_ALREADY_RETURNED" .... okay now what the heck does this mean? I spent $80 on an ebook from McGraw-Hill and the stupid DRM (Digital Rights MIS-Management) acts into play and locks me out of viewing my own eBook... okay Adobe..fix this!!!!
This indicates that the store sold you a book that was returnable (ie like a library book) and that you returned it, or that they did not give you a unique transactionid. I would suggest that you talk to the store in question to see if they will issue you a new download link.
