My first post after being a long-term lurker.
The same issue happened to me. Lost my entire HD suite except HBO. fter about two hours on the phone they discovered they had a major computer glitch that put a disconnect code on the HD channels on many accounts. They ha to jump through a few hoops, but got it turned back on eventually.
So, do not pay for a service call for this issue.
Phenomenal. I just talked to someone who knew what she was doing and got it all squared away. Thanks!
