So, I updated the firmware on my old Acvtivhub to V5.13 B0. The Activexpressions are working just fine since the update. The self-paced questions move on to the next and there are zero issues. The issue is indeed the old firmware. I had to update from home as my school has a firewall that doesn't allow me to access the files to update the Activhub.
Thanks for the input everyone. I hope this answers your question. All the best in your assessments, this truly is an amazing tool.
