Hi,

I'm experiencing the same problem even after checking the "Allow conversion to complete even if errors are detected" checkbox.

Calibre, KFX Input and DeDRM are up to date.

That's the error message:

ERROR: KFX conversion failed
Cannot convert "Book Name"
TypeError("unsupported operand type(s) for *: 'NoneType' and 'Decimal'",)

I loaded the KFX from Kindle PC 1.24. Loading from the device is not an option right now becasue my firmware is 5.10.2.1.

Any ideas how I can handle this? Thanks.
