Xfinity stream (Error xacsa.xact.3370.1000937: FatalDrmError)
I have been getting this same message for months and the "techs" at Comcast cannot figure it out.
We apologize that you are experiencing this issue. We recommend that you reset your Adobe Flash License in order to get this error cleared. For more information on how that is done, see here: https://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager08.html
I had this issue of the "Error xacsa.xact.3370.1000937: FatalDrmError" when trying to access Xfinity Stream using my Chrome browser for days after signing up for Xfinity TV. All the potential solutions recommended on this forum did not work for me. I called Comcast Support and went through Tier 1, 2 and Tier 3 support and all the gyrations recommended.. Unfortunately the problem never changed. Updating Flash, deleting cash over and over again then resetting Chrome to original default settings via the Setting Menu never changed the problem.
