#1 cannot find main class

[GRboss]

I downloaded and installed it. First it asked me some questions but i pressed cancel to all of them because i did not want/know to answer.
The program did not start. Ever since i try to launch it an operating system window pops up and says:
"Could not find the main class. Program will exit"

Please reply to my post at grbosss@yahoo.com or at skapiris@csd.auth.gr.
I need your reply for a university project.

Thank you in advance,
GRboss

THe Problem Is That The Program Requires JRE 1.5 At The Least, While You Are Problably Running 1.4 or earlier.
