Hi:
The directions in the REQUIRED set up instructions tell you exactly how to LOAD the data. The setup instructions have 4 pages in a PDF file. Page 3 is where it shows how to LOAD the tables. Please look here:
You can't just start the servers, you also must load the tables. In a production environment, you would probably have a systems team to do this for the company. However, when you use the Amazon Virtual Lab, it is the student's responsibility to START the LASR servers and LOAD the tables.
Hope this helps,
Cynthia
