I've tried everything the internet told me to, and still I cannot purge this horrendous DRM from some books my husband bought for me, but innocently downloaded to his account.

This Epubor almost helped me, but when I insert my kindle serial number, it says it's wrong - but I am inserting the numbers as they appear on the device and on my amazon account as well... if you guys know what could possibly be the problem, please contact me. I am so frustrated that I cannot read the books my husband gave me as gifts because of the narrow-mindedness of these enfuriating companies.

Thank you very much.

Martha

Just to make sure: You entered the Kindle's serial number without any blanks? Because on the website as well as in the device's menu it appears divided into groups of four digits separated by blank characters. The Un-DRM software on the other hand needs the serial number as just one sequence of characters/digits without any separation...

Try again!

Doesn't work for me either. I entered my serial number with comma's as separators and with no space or comma's (One line of characters) and it failed. No idea what to do next

Hi John,

A Kindle Serial Number is 16 digits with number and characters, like A1B2 C3D4 E5F6 G7H8

Then you just input the KSN as A1B2C3D4E5F6G7H8

However, you can try our latest version program, it support directly reads KSN from Kindle, no need to input the KSN manually anymore.

If have further problem, please open a ticket at ticket.epubor.com

I just paid for the upgrade and tried running the decryption and all of the e-books were moved to the "decrypted" folder still fully encrypted. My serial number is entered correctly, I followed all of the steps on the website, and still it doesn't work. Looks like I'll need to request a refund and find another decrypting software that actually works.
