Problem of Nerovision API's sample

There is no problem that runed Nerovision API’s Sample program with Project type “vcd” after this sample compile.
But if you run this sample program with project type “dvd”, occur exception in this line :

Class :: CPageSecond
Function :: OnChangeState

bSuccess = pPageData->m_pProject->EstimateCreateNeroBurnContextTime (this, &dSeconds);

And I attach my libray version.

Nero SDK 1.08
Nero 6.6.1.4
VisionExpress 3.1.0.25

I have the same problem
I you know something please let me know.
Regards.
