    I have the same problem trying to add a Chinese book, also from google play, where the acsm name has Chinese characters. I’m getting the same error, and support via chat from both from google play and adobe have had me try numerous things to no avail. I hope there is a solution. I am on a mac platform.

    Where can I get directed support from adobe? I only have support from google play. But they say I have to contact Adobe. Anyway, I try to open the “Sample book” from Adobe, and it work, but not my book I want to read.
