I've got an original Fire that is unrooted. I also use Calibre. When I go to Amazon and download my purchases to my computer then try to import them into Calibre I get the following message.

K4MobileDeDRM v0.4.2 Plugin
Error: No key found. Please report this failure for help.

I do have my serial # loaded into the K4PC, K4MAC, etc plug in under "File Type Plugins". Any other suggestions???
