I've been at this for four and a half hours now and still can't figure it out, so I figured I'd give this a shot. Basically I'm having issues getting ADE to recognize my Nook device in order to download books onto it. I tried reached out to B&N tech support, and they said that it likely had something to do with my computer, as my Nook has the most up to date software update. So I tried using a completely different computer (was using Mac before, am now using a Windows), and it STILL isn't recognizing my Nook.
I don't know why this is an issue, since last week I had no problem using my USB in order to download books from ADE. But when I tried this week, not only will it not work, but it also completely deleted the books i had downloaded on my Nook device. I'm just super confused and I wish this was more user-friendly.
I figure it is not an issue with my Kobo reader, as it is not plugged in and the Adobe Digital Editions will not work. I download the book no problem on my computer. It's when I want to open it on ADE that is the problem. It tells me error! check activation. I see all the other books I read before on the background. I can open the book from the library site and it will open on my computer so I can read it there. The problem is I want it on my KOBO! ADE what is wrong with your program!!!
