Did you get a (D)KDM for this encrypted DCP? Without a (D)KDM, you can't do anything useful with it.

Hi, that's an error related to the HMAC (a thing to check the integrity of the data). Is it possible you have a corrupted DCP? I have in the past made test versions of DCP-o-matic which ignore the HMAC on reading, but more errors usually follow. How did you receive the DCP? Can you open it in the player and do a verify?
