It wasn't a premium channel problem (don't have any premiums) - it was my HD extra preferred channel package (like USAHD, TNTHD, TBSHD, etc). The error message on the channels that wouldn't come in was just that typical you are not authorized for this channel, contact your cable company with a phone number listed. The conditional access screen showed a few different things depending on the cable card. The AUTH: section has said FWK when I wasn't getting all the channels. It also has said MP.
