Hi César,
You have to authenticate with the card key which is used to protect the read command (it there is any). It is no need that this is the master key. I would never use the master key for the access control of files! The master key should only be used for administrative tasks like change keys etc.
You have to initialize the software keystore before you can use the keys. This is done usually in the createView() or resume() methods.
The error message indicates that the value used clashes with the key type definition.
