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.

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
