DirectX AudioVideoPlayback error

Question

Hi all,

I am using the DirectX AudioVideoPlayback dll. However I get the following error when trying to initialise the Audio object

System.Runtime.InteropServices.SEHException
Message: External component has thrown an exception.
Source: Microsoft.DirectX.AudioVideoPlayback
StackTrace:
at CreateWindowExW(UInt32 , UInt16* , UInt16* , UInt32 , Int32 , Int32 , Int32 , Int32 , HWND__* , HMENU__* , HINSTANCE__* , Void* )
at Microsoft.DirectX.AudioVideoPlayback.Audio.CreateCoverWindow()
at Microsoft.DirectX.AudioVideoPlayback.Audio..ctor(String fileName)

I do not understand this error. I am sure that the filepath to the media item is correct.

Any ideas?

thanks in advance
