How to access keysight plug in development course?

I want to view the material in this course, here.

I created an account, and I registered. However, when I open the course, I keep seeing adobe refused to connect. Adobe is not being blocked, and I enabled all trackers. I also tried on another computer, with the same behavior.

Do I need to contact the Keysight sales team to get a course license? Or does someone have the course material in an alternative format?

That is a paid course from Keysight so you do need a license for it.
