Protected audio

Ok so I got DTV2PC a while ago on my laptop. When I first got it I got the error. "The video's audio is protected and requires an audio driver with HDCP support; changing the audio output to analog might allow audio playback."

Well I read online and I changed the way my computer playedback and since then I have been able to stream and watch HD television on my DTV2PC for about 3 months now.

Well now it is suddenlly giving me that message again although my settings I changed a while back are still the same.

I remember updating my computer though and I saw an update for IDT- Audio- IDT High Definition Audio CODEC.

Could that update be causeing the problem. I looked but could not find a way to revert back on that update even through "Installed Updates"
