I too am an ebook user; started with a Sony PRS-T1 reader and switched to a KOBO reader. I went through such a hassle trying to get my Adobe authorization transferred to my new Kobo, and now, guess what--I can't read any of the books I have on the Sony, using the Kobo, or vice-versa. I was really teed off at Sony for abandoning their ebook sales, after I spent what to me was a fortune on books for their reader, but I guess that was their decision. I'll never buy the Sony tablet, computer or phone I was planning to purchase. The Kobo works fine and (thankfully) so does my original Sony, though I can't use just one or the other for all my books
This makes me angry; what it amounts to is interference by Adobe to block my reading of books I've bought and paid for.
I haven't tried to force open the ebooks and work around the DRM authorization, not smart enough. If you find a way to do this, please will you let me know. I have tried to play by Adobe's rules and it has cost me access to most of my ebook library. I'm really disgusted, as I can see that you are. I wish we could start a class-action suit against Adobe.
Anyway, I know from reading the forum entries that I'm not nearly alone in this. If you have any luck solving your (our) problems, will you please let me know.
Thanks very much.
There are a few available drm-removal tools on the internet. A google search will help you find them (avoid the sites that look suspicious, and always make sure you have an antivirus on your pc). Most are "30-day trial", after which you will have to pay for them. I found a freeware tool but it does not work well, some of my converted books lost entire chapters! So it is not enough to get a "success" message. If you chose to get a paying software, use the free trial period to convert the books you already have and see if they got converted correctly.
The drm-removal process is very easy: open your epub files with the tool you have downloaded and installed. It will create a new epub (usually with the same name but in another folder. That new file is practically identical to the original, but without the protection. You'll then have to copy manually the book onto your reader.
Therefore Adobe Digital Editions is only used to download the book from where you have bought it. Otherwise it becomes a useless piece of software. Isn't that sad?
Now, I don't know in detail what the "legal" rules are. I guess the intention was to emulate the single "paper" book that may change hands but never gets duplicated. It's like software, you get a licence to have and use a single copy of it. So removing the drm-protection is not illegal in itself (someone please correct me if I'm wrong). If you only keep one copy of your ebook at a time (i.e. if you copy it on your sony reader then you should erase it from the kobo) you should be ok with laws. It may be enough to make sure that while you are using one reader, the other is turned of and laying unused in a drawer. You can of course keep all ebooks on your pc as they are considered backup copies.
Hope this all helps!
Thanks, Thierry, for the information. I do get frustrated, and I live for
the day when I can open any book I own on either reader. May that day
I am keeping your email and will dig into it.
