I am a sbuscriber to Scientific American Digital. I can download the pdf file andusing Caliber viewer I can view it. But if I attempt to send it to a device, It shows working and progress shows unavailable. I waited over 10 minutes and ended up having to close the program. Has someone encountered this problem and know how to get around it. I also tried converting the file to epub format. Same problem
Any help will be greatly appreciated
