Can not create new reports

I have a license SOAP UI 3.6 Pro.

I need to create a new Report. When I type the Report name, select the type as <custom>, click "OK" button, select subreport and click "OK" button. The create new Report Window is not closing and the new Report is also not created.

The console launch the next error:

java.lang.NullPointerException
at com.eviware.soapui.reporting.support.DefaultReportingContainer.hasReport(SourceFile:113)

Thanks,

Juan M.M.

PD: Ole...help me....
