Roku 3 not working with Instant TV

[EL1111]

Getting message: "Unfortunately, we cannot support high speed data customers without a video subscription." (Error: createDrmSession, -1) on Roku 3.

Instant TV works on phone. And yes, I do have TV and internet service from Comcast.

I found another thread that addresses this but can't find a way to "reply" to the thread or PM the Comcast employee as instructed in that thread. Thread was active last month and not marked "solved". This is rediculous!
