Error: Encryption Removal Failed

Help from anybody. I was able to use unswindlev7 for amz files. I am using K4PC beta 1.01.

When I use unswindle it says I can't decrypt topaz files.
There is no topaz tools in the current DRM Tools Archive 3.4, so I used kindlebooks.py in kindletools.

The above is the error. It's as if Amazon upgraded their topaz encryption so the current version of tools cannot get around them.

Please help.
