Hi
Some days ago I found the introduction to Radioss course imparted by Paul Du Bois in 2008,
below I show some example of the videos

but today I am not able to find the videos because somehow the links are now invalid , when I click on the link, it leads me to the Altair Academic Programa home page, I will show some links here, *none of them work*.

Can you help me? thanks.
Edit: I think the web
https://altairuniversity.com/learning-library/
(Altair Learning Library)
is no longer available, maybe I know why?
