Error with Academy VM: Component stack mismatch in pzLPApplicationDashboard
For the first exercise "Configuring a case type" in the Business Architect Essentials training, I've downloaded and installed the Academy VM C1225-1312 with Pega v8.1.1 (since the online Pega Cloud exercise system didn't work for me). I'm running it on VirtualBox. The Linux machine boots normally. After I launch the App Studio in my browser and login with author_cm@gogoroad, the screen is blank. When I click on "Application Overview" I get the following error:

Display error

When I click anywhere else, the UI freezes...
The Dev Studio seems to work a little better: I can browse the application rules and types. However, it also fails as soon as I try to create a new Case Type. I receive a pop-up with the message "There has been an issue; please consult your system administrator".
How can I solve this issue? Especially, how can I get the App Studio operational to do the exercise?
