error C2594: 'static_cast' and Multiple Inheritance

Hello,

I am trying to add a connection point to one of my already existing
class.
I can't get rid of the C2594: error.

I got a class template that I use for several class:

template <class T>
class ILanguageImpl : public T
{
public:
  STDMETHODIMP get_Language(LONG* pVal)
 { ... }

};

Here is the class I add the connection point:

class ATL_NO_VTABLE CTranslator :
    public CComObjectRootEx<CComSingleThreadModel>,
    public CComCoClass<CTranslator, &CLSID_Translator>,
    public IConnectionPointContainerImpl<CTranslator>,
    public CProxy_ITranslatorEvents<CTranslator>,
       public ILanguageImpl< IDispatchImpl< ITranslator,
&IID_ITranslator, &LIBID_InterfaceLib > >
{

DECLARE_REGISTRY_RESOURCEID(IDR_TRANSLATOR)

BEGIN_COM_MAP(CATRTranslator)
    COM_INTERFACE_ENTRY(ITranslator)
    COM_INTERFACE_ENTRY(IDispatch)
    COM_INTERFACE_ENTRY(IConnectionPointContainer)
END_COM_MAP()

BEGIN_CONNECTION_POINT_MAP(CTranslator)
    CONNECTION_POINT_ENTRY(__uuidof(_ITranslatorEvents))
END_CONNECTION_POINT_MAP()

..... };

The problem occures when I create a COM interface pointers.
CComPtr<CTranslator> moTranslations;

error C2594: 'argument' : ambiguous conversions from 'CTranslator *' to
'IUnknown *'

I understand that when I try to create the COM interface pointer, it
can not choose between the ILanguageImpl and CProxy_ITranslatorEvents
IUnknow pointer.

Is there a way to "cast" which IUnknow pointer to use when creating the
 CTranslator Class?

Thanks,
