Ebooks from Sony PC Reader to Adobe Digital Editions

Question

I have a Sony PRS-T1. I also have Adobe Digital Editions installed on my computer. My Husband has a Kobo. When I purchase ebooks from various book stores they are automatically put into Sony PC Reader. When my husband wants ro read these books, I add them to ADE and then drop them onto his ereader (which appears as a book shelf). Recently when I have done this he has been unable to open the ebook on his device. Now I am noticing that when I try to put the ebook onto ADE, it gives me an error message that the "document is licensed for a different device". How do I fix this?
My understanding is that I can add the book to up to 6 devices, I am just trying to add it to a second device, and this has worked perfectly in the past????
Is there any way to avoid using Sony PC Reader ( I don't like it) and just use ADE to up load ebooks from the retailer and then to my Sony and the Kobo???

Answer 1

Unfortunately, the error comes from ADE reading the ID file of the ebooks
and then comparing it to the current ID.  That's the only time the error is
generated.  And it's possible that something has screwed up due to a change
that seemed unrelated.
Let's take this a step further.
If something 'changed' recently, did you log into the Sony Reader Store in
that time frame?  Sony has updated their software, and that can occur
without you seeing anything happening.
Have you been able to open any of the affected ebooks before?  Where did
you download them from - and if it was Sony Reader Store, did you put them
into the Reader library?
Did you know that Sony tells us the PRS-T1 is not supported under ADE,
while ADE says it is?  I don't know how to rectify that.
Did you register the T1 with Sony using your current Adobe ID? (you
probably did but I had to ask)
Often, I forget a detail that, when I remember it, gives me the key to the
answer.  I've been doing that for a number of years, but my wife doesn't
give me credit for any of them.
