Restricted Content on premium channels

[AATech]

hi, i am running windows media center on windows vista hooked up to a
scientific atlanta cable box. most of the times i try, i am unable to watch
content on the premium channels, or shows recorded to the DVR from the
premium channels. i get the error:
"Restricted Content - Restrictions set by the broadcaster or the originator
of the content prohibit playback of this program on this computer."
non-premium cable channels work fine.
Upgrading the DRM security components at
http://drmlicense.one.microsoft.com/Indivsite/en/indivit.asp?force=1 didnt
work

resetting the drm with this program:
http://go.microsoft.com/fwlink?linkid=105000

didnt work.

any ideas?

Thanks,
Al
