This message has been coming up everytime I open up my Adobe digital editions. Whenever I try downloading a .acsm book, nothing happens. Epub books download fine. I've altered my firewall, as per adobe's instrutions & my Kaspersky anti-virus has also been altered as per Adobe's instructions. The time was not changed on my computer at all. Suddenly, I just can't download .acsm ebooks, from the 12th of October 2011, which I had no problem downloading before. The .acsm books already in my library can be read just fine. I've tried downloading .acsm books from various sites, also Adobe's, but NOTHING happens!!!!!!!!
What can I do? I had purchased books, which I cannot read now.
