I'm a long time digital subscriber and (as of this morning) I have the same problem.  A couple of weeks ago, I could access the instructional videos but not now.  Somebody on the programming side hit a wrong button somewhere.  Hopefully access will be restored soon.

I don't know what changed, but something did. Digital Subscribers should have access to all the videos.

I've submitted a tech support ticket to Crowdstack.

Crowdstack Tech Support confirms this is a bug in the software, likely caused by the changes made to the processing and handling of premium content in the Social Home Page Release they did last week.

Here is a portion of their response on my Tech Support ticket: "...I would anticipate a resolution to this some time around mid-to-late next week..."

There ya go.

This has been fixed.
