TestNeroCBUI crashes, problem with CoCreateInstance

Hello,
I am using Win2000 and VC6.0. The following line (#123) of code from the TestNeroCBUI.cpp file fails for some unknown reason. The app will compile and run but most of the buttons will cause an exception and crash the program.

SUCCEEDED (m_pInitSettings.CoCreateInstance (__uuidof (InitSettings))

I stepped through the execution with the debugger and found that CoInitializeEx() returned S_OK. Also the NeroAPI was succesfully initialized. I have not modified the test app in any way. Does anyone have any thoughts on what is causing this problem.
