Question:

Good Morning! I am trying to download the offline program to read my ebook
purchased last week. I only get errors when I click on the download icon,
and when I manually try to download the file I get a file with no
extension, so my computers cannot open. My computers are running Windows 7
64 bit OS.
I look forward to hearing from you and getting help!
Thanks
