Hello.

It doesn't works in Calibre 2.17 (64bits) in Windows 7. I get this:

calibre, version 2.17.0
ERROR: Excepción no considerada: <b>TypeError</b>:%d format: a number is required, not NoneType

calibre 2.17 [64bit]  isfrozen: True is64bit: True

TypeError: %d format: a number is required, not NoneType

and with the second button:
