I am getting the error message "

Error getting License. License Server Communication Problem:

E_LIC_ALREADY_FULFILLED_BY_ANOTHER_USER* on a MAc with OS El Capitan. I want to convert some ACSM files but am receiving this error message.

You get the error that fulfilled by another User when the eBook are linked with a other Adobe ID.

Often its happens when you open/download a eBook before you authorize Digital Edition. Then

authorize and can the eBook no longer read.
