OMNET++: error in module cModule during network setup

I'm trying to run my first Castalia/WSN simulation (testRouting) in Omnet++. I have created the 3 folders (TestRouting.h , TestRouting.cc and TestRouting.ned) and the .ini file and I have fixed errors that appears at the omnet IDE.

But next, I can’t start the simulation because of this error.

Error in module (cModule) SN.node[0].Communication (id=10) during network setup: Submodule Routing: no module type named 'TestRouting' found that implements module interface node.communication.routing.iRouting(not in the loaded NED files ?), at omnetpp-4.6/samples/castalia/src/node/communication/CommunicationModule.ned:32.

Can you help me?
