No cross section is registered for gamma

I use this code in GammaNuclearPhysics.cc in example Hadr03

void GammaNuclearPhysicsLEND::ConstructProcess()
{
G4ProcessManager* pManager = G4Gamma::Gamma()->GetProcessManager();
//
//G4PhotoNuclearProcess* process = new G4PhotoNuclearProcess();
//
G4PhotoFissionProcess* process = new G4PhotoFissionProcess();
G4LENDorBERTModel* lend = new G4LENDorBERTModel(G4Gamma::Gamma());
lend->SetMaxEnergy(20MeV);
process->RegisterMe(lend);
//
//G4LENDCombinedCrossSection
lendXS = new G4LENDCombinedCrossSection(G4Gamma::Gamma());
G4LENDFissionCrossSection* lendXS = new G4LENDFissionCrossSection(G4Gamma::Gamma());
process->AddDataSet(lendXS);
//
pManager->AddDiscreteProcess(process);
}

After compiling and running there are shown the next message:

-------- EEEE ------- G4Exception-START -------- EEEE -------
*** G4Exception : had001

*** Fatal Exception *** core dump ***

How solve the problem ?

did you downloaded LEND data set ( from ftp://gdo-nuclear.ucllnl.org/) ?
If so, send a mail to dennis.herbert.wright@cern.ch
