As part of an upcoming software download, the C61K client’s authentication procedures will be changing, which means the client’s software needs to be updated before it can display 4K content. Previously, the C61K was only authenticated at the time of the initial pairing with the server, but now, authentication will be performed each time the client plays 4K content. We are making this change to maintain security compliance with our content providers.
It will be critical to ensure that the C61K client has updated to the most recent version of software PRIOR to attempting to verify 4K content. Failure to do so will result in the following error: “This program cannot be authorized for viewing at this location. Cannot Authorize.” The C61K will display HD programming before the software download commences.
