Error: Launching planning modeler

Hi.....when we try to launch planning modeler, we are routed to the below portal link.

http://IP address:50000/irj/portal/webdynpro/dispatcher/sap.com/bi_planworkbench1/Modeler

What should be done to get connected to the planning modeler screen where we can create aggregation levels.
