iReport error attempting to modify a Unified Report

I've been trying to find a way to create an availability report for network devices with teh following criteria:


Event Status (Green/Red)


IP Address

Up or Down - Based on net_connect alarm state.  Critical=Down or else Up


I installed iReport 4.5.1 last night and believe I have most of the features working (with a couple minor exceptions for another thread :-)).  I'm able to connect to the jasper repository and view the Nimsoft folders from iReport . 


From Unified Reports I made a copy of the Top 20 Hosts by Response Time and I see the copied report in iReport.  I'm attempting to edit the report using iReport, however whenever I try and open the Main.jrxml file I receive the following error:


Error loading the report template:

net.sf.jasperreports.engine.JRRuntimeException: No query executer

factory registered for the 'NimsoftJSONTopN' language


The error seems generally straightforward however I'm not sure what I need to do in order to resove the error and be able to modify this report.  On a side note I've installed iReport on my PC and is not installed on the Nimsoft Web server. 


Any help on either creating an Availability Report or getting this error resolved would be appreciated!
