Hey Gabriel, here is my tutorial for creating dashboards, packaging them and deploying them in SAP Business One: Crystal Dashboard Design (Xcelsius Dashboards) for SAP Business One Training Tutorial - YouTube
In terms of the tutorial you are referring to I think it's outdated. My key came from SAP and is an NFR (Not For Resales) SAP Partners key.
Check my YouTube video for more details on Crystal Dashboard Design. Thanks!
Mike
