What does this mean. I was able to download a book last week and now I get this error. Does it have anything to do with the latest Firefox version?
Yep it was the computer date/time that was not correct. Once that was corrected everything worked perfectly.
this worked for me
Sorting the time zone issue also made it work for me with a Macbook pro OSX Mavericks, thanks a lot!
This worked for me finally! Macs
