VM console screen is blank for C1225-1312.ova
I have downloaded Exercise System C1225-1312.ova for System Architect Essentials Version: 8, imported it into VirtualBox 6.0 per http://pegasystems2.http.internapcdn.net/pegasystems2/exercise_guides/Pega_Academy_Virtual_Machine_User_Guide.pdf. When I start VM, VirtualBox will open a new console, but the console will remain blank without the expected course information and URL. Hence, I am unable to do the course exercises. How can I resolve the VM issue? Thanks.
