Adobe Digital Publication licensed. E_ADEPT_REQUEST_EXPIRED error

[Taitawanta]

Hello. I am Adobe Digital Publication licensed and authorized but not let me download my ebook. I get this message. E_ADEPT_REQUEST_EXPIRED. Today I deleted and re-request authorization but still gives me the same error. My PC is in the right place and time according to my country coordinates. What else can I do?

Check also Date and Timezone. The both are often also the cause of the error.
