Hello Sarah,If you are sure that the environment variables are OK, try to work on your PhysicsList. I solved the problem by adding this code in ConstructEM(),

.....
else if(particleName == "GenericIon"||
		(particleName=="nucleus" && (particle->GetPDGCharge() != 0.0) ))
	{

	//multiple scattering
	pmanager->AddProcess(new G4hMultipleScattering,-1,1,1);
	//pmanager->AddProcess(new G4MultipleScattering(),-1,1,1);

	//ionisation
	//G4ionIonisation* ionIoni = new G4ionIonisation();
	//ionIoni->SetEmModel(new G4IonParametrisedLossModel());
	//ionIoni->SetStepFunction(0.1, 20*um);
	//pmanager->AddProcess(ionIoni,-1, 2, 2);

	 G4hLowEnergyIonisation* ionesLowEnerIon = new G4hLowEnergyIonisation();        
	 pmanager->AddProcess(ionesLowEnerIon, -1,2,2);
	 ionesLowEnerIon->ActivateAugerElectronProduction(true);
	 ionesLowEnerIon->SetNuclearStoppingPowerModel("ICRU_R49");
	 //ionesLowEnerIon->SetNuclearStoppingPowerModel("Ziegler1985");
	 //ionesLowEnerIon->SetNuclearStoppingOff();
	 ionesLowEnerIon->SetNuclearStoppingOn();
	 ionesLowEnerIon->SetElectronicStoppingPowerModel(particle,"ICRU_R49p");
	 ionesLowEnerIon->SetCutForAugerElectrons(10*eV);

	}
	else if .....

goog luck! Javier
