Problem z aplikacją mfc

Witam,

Mam problem z aplikacją ADO(Ćwiczenie z książki Visual c++ 6 dla każdego). Po skompilowaniu nie ma żadnych błędów oraz ostrzeżeń a program po uruchomieniu od razu się wywala...

void CBdAdoDoc::DeleteContents()
{
if(m_pRs)
m_pRs->Close();
if(m_piAdoRecordBinding)
m_piAdoRecordBinding->Release(); (tutaj się wywala program)

m_pRs = NULL;
CoUninitialize();

CDocument::DeleteContents();

}

To się pojawia po debugowaniu:
