I have Windows7 OS and want to use **MEKA GUI** what I did is the following:

1. downloading meka-release1.5.zip from <http://sourceforge.net/projects/meka/files/meka-1.5.0/>
2. extracting it, and type run.bat in cmd.exe

But I had the following Error :

> 
> Error: Could not find or load main class .\lib\Jama.jar
> 
> 
> 

Can any one help with clear steps how to install and use MEKA EXplorer?
