soapUI Bug - Interface issues

I downloaded open source version from http://sourceforge.net/projects/soapui/

I was able to open the application.But, I cannot create a new soap project.When I create new project , I just see "new project dialog" box without check boxes.Also , I observed many other errors in the error log.Most them were swing and awt exceptions

I need to use SoapUI with Heremes JMS in my windows xp sp3 machine.
