Hello Santiago,
These tutorials are no longer available and most of the content was old and related to the old LS-PrePost GUI.
You can find more recent LSPP training material here:
https://ftp.lstc.com/anonymous/outgoing/lsprepost/Training/Intro/
Also, most of the information from lstc.com can now be found at lsdyna.ansys.com
Let me know if this helps or not.
Reno.
