Gamebryo: Program crash when render NiMeshScreenElements

I use NiMeshScreenElements of Gamebryo to render 2D image in Game, First, I Create NiMeshScreenElements from a png file, and then rend this NiMeshScreenElements. Gamebyro popup an error dialog when rend the NiMeshScreenElements.


NiMeshScreenElements * g_pScreenElement;
bool GImage::LoadImageFromFile( const char * pszPath )
{
NiFile * pkFile = NiFile::GetFile( pszPath, NiFile::READ_ONLY );
if( pkFile == NULL )
return false;
NiPNGReader pngReader;
NiPixelData * pSrcData = pngReader.ReadFile( *pkFile, NULL );
if( pSrcData == NULL )
return false;
NiSourceTexture * pSrc = NiSourceTexture::Create( pSrcData );
if( pSrc == NULL )
return false;
g_pScreenElement = NiMeshScreenElements::Create( pSrc);
return true;
}

g_pScreenElement->m_eColorFormat become F_FLOAT32_4 after executing above code. I suspect that is a error value.

and then I render NiMeshScreenElements * g_pScreenElement .

m_pDevice->SetScreenSpaceCameraData();
g_pScreenElement->RemoveAll();
g_pScreenElement->AddNewScreenRect( (short)fX, (short)fY, (short)fWidth, (short)fHeight, 0, 0, NiColorA::WHITE );
g_pScreenElement->RenderImmediate( m_pDevice ); //popup an error dialog when execute this line


popup error dialog as follow:
NiVerifyStaticCast() caught an invalid type cast
Stack Trace:
NiObject::VerifyStaticCastDebug
NiD3DShader::PreRenderSubmesh

Thanks
