I am having the same issue here, installed update and now nothing appears when the drawings tab is selected in a project.
Has anyone had any luck resolving this issue?

Same here but with only one of eigth machines: open SD 7.1 after latest update, create new project, go to "Drawings" tab: nothing there but the two titles "Available templates" and "Current drawings"...

I'm trying to investigate on my own, and it seems that all of my modules that I'm subscribed to are gone. My USB dongle is plugged in, and my PC recognizes it. I am signed in with the correct email address. When I create a new drawing, the only template I have available to me is "Plan View". 

Today Design 7.1 prompted me to install a new update. I did, and now none of my project files have any of the drawings that they should, there are no drawings in the drawing tabs. How can I restore my files to the way they were before this update?
