Can not download eBook from Virtual Classroom

When I try to download the eBook from a RH Virtual Classroom course, I get a pop-up which says:
"Preparing eBook
The first time you request a student guide eBook, it may take up to 15 minutes to process your request."

However, that window never goes away, despite waiting for hours. I have tried two browsers (Chrome and Firefox, both on RHEL7). I tried again after disabling pop-ups.

My ID with a RHLS attached is not the one I am using to create this discussion. For some reason I can't open a case (403 error) or start a discussion with that ID (the button doesn't exist).

Anyway, I'm interested in any suggestions about how I might go about getting this fixed, please...
