Error: Could not find or load main class Main

[GoogleCodeExporter]

What is the expected output? What do you see instead?
When I try to run the run.sh I get the above error.

What version of the product are you using? On what operating system?
program-ab-0.0.4.3 on Snow Leopard (mac) running java 7

Please provide any additional information below.
I am really newbie so the solution might be obvious but I would appreciate the 
help.
I have followed every step but still getting this error, am I missing something?
