Analyst - Online Course - Create an Application

I am trying to study for the Analyst qualification. As part of this I am using the Online Course. I need to go through this Online Course a number of times to fully understand the concepts. Unfortunately there are some parts that will no longer load once the course has been completed the first time. Most notable of these is "Create an Application". The page partially loads and then freezes and I must exit to continue.

Another, that I have found so far, is Application Architecture, Quiz (the second one, after Personas and Groups).

Kind regards,

Glyn
