Have been trying everything I can think of like uninstalling reader library and reinstalling it but the authorized names(email address remains the same) I cannot find the adobe application on MAC and adobe website says I must ring them to change anything which is a bit awkward as I am in Ireland and they are in USA what with time difference and holiday season

The first thing to do in this situation will be to clear the usernames which the system has stored in it. Not sure how this can be achieved in MAC but on windows you go to file> options > security or browser history and when you open them you clear all stored information.
After clearing all the information you can enter your information afresh like you want to sign in and it should work. Hope this solution has been helpful?

Hi Jimswings,This just indicates that the ebook reader is still authorized to the previous user. Luckily, you are able to de-authorize it so it will erase all of the previous user's information and you'll be able to authorize it for your use. I've provided the steps below to de-authorize - hope this helps (this is done via the Sony eReader Store when connected via USB). Once complete, you can then go through the steps of authorizing your reader to you and transfer books!

To de-authorize the Reader device If you provide the Reader device to another person, you need to de-authorize it from your account.
  1. Turn on the Reader device, then connect the Reader device to your computer using the supplied USB cable. "Reader" appears in the Source view.
  2. Click "eBook Store" in the Source view. The View area is switched to the Store view.
  3. Click "My Account," then follow the store instructions to de-authorize the Reader device.

I can't download my ebooks onto my reader, I have a bunch of books on my computer from kobo and I've tried everything I can think of to transfer them to my reader, loaded adobe digital, trying to load them...

Most readers have their own unique email address. You can try to send some books to that email address and see if they become available to the reader that way. Could take a while if you have a bunch of books though. The email address is in the settings of your reader. Depending on the reader you have it will be in a different location.

How do i retrieve my device lock password for my SONY PRS- 600?

I'm not sure if you're looking for your password to the Sony Ebook Store authorization or your password when you purchase a book. Here are both solutions:
Password for Sony Authorization - You will need to connect your device to your computer via USB and then log-into the Sony Store. If you don't know your password, simply select "forgot password" and it will be sent to you. - Then you can log-in and authorize your device (it will be on your "home" screen when you log-in properly if you need to authorize your account)
Lock Password for Books - This is the credit card number you used when you purchased the ebook

The books I downloaded will not transfer to my reader, the stutus circle isn't moving to indicate the books are being sownloaded.

I have answered this question here:
Here are the steps: I was having the same problem, here is the solution!!! Apparently there were some updates made by Adobe that needed Sony e-readers to re-authorize their accounts. Not convenient, I know, but here's the easiest way to fix it.
  1. In your library, delete the new books that you imported since it stopped working (make sure you have them saved somewhere else or are accessible from the purchase store)
  2. Close out the Reader Library application and disconnect your e-reader.
  3. Re-connect your device via USB port to your computer (no waiting time needed).
  4. Go to the ebook store icon on the left-hand side > then in the ebook store page, select "sign-in"
  5. When you sign-in, you'll see a note indicating that your device is not authorized. Select "Authorize"
  6. Once you've selected this, go back to the Library screen.
  7. Import your files once again and then you should be able to drag and drop them back to your e-reader.

I downloaded some ebooks from waterstones to my pc with no problems,but when i transferred them to my ereader the books are blocked under copyright,how do i register my ereader with my pc, regards

To transfer books from a computer to the Reader, you must authorize the Reader to your account. Authorization links your Reader to your eBook Store account, allowing books purchased from the eBook Store to be transferred to the authorized Reader. You can authorize up to six devices to a single account.
  1. Launch the Reader (eBook) Library software.
  2. Log in to your eBook Store account.
  3. Turn on the Reader. NOTE: For best results, we recommend that the Reader be fully charged before starting the authorization process.
  4. Connect the Reader to the computer.
  5. In the eBook Store pane, click My account .
  6. On the Account Management page, under My Authorized Devices , click Manage Devices .
  7. On the Manage Device page, under We have detected the following attached Devices: , click the Authorize this device button.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it and give a testimonial for my response. Happy Holidays!

Thanks, Joe

Word Doc opening problem

Refer to the following if you are unable to read an eBook.

* Copyright-protected material (books, and documents, etc.) will not open on any device other than the device or devices authorized to view the material. Copy protection also applies to material stored on removable media (Memory Stick or CompactFlash media).
* In cases of Adobe DRM protected content, authorization may not have completed and an Adobe ID obtained. Install or re-authorize your computer, the Reader and Adobe DRM protected content.
* Authorization may not have been performed. Authorization is necessary for reading eBooks. Authorize your computer and authorize your Reader to the eBook Store.
* The content owned by another user cannot be read.
* The authorization data may be damaged caused by a shut down while reading an eBook. De-authorize your computer and de-authorize the Reader, then authorize again.

Hi, the error message is displayed when the Reader is authorized with a different account(i.e. a Reader cannot be authorized with more than one account). However, if you purchase a new Reader, the Reader should be authorized with ytour account. BTW, from where did you download the EPUB formatted book??? In order totransfer the book to the Reader the Book should be downloaded from the same account where the Reader uis authorized with. However, I want some detail with this rehgards like from where did you download the book, Reader is authorized with the same account or not, whether you have purchased a new Reader or this is refurbished one. Please getr back to me with those questions, I'll be glad to assist you with this.
