calling .net assembly DLL methods

[4play]

I have a .net assembly DLL that throws an error when one of the methods are called.  To retrieve info from the device under test, a request for the property must be issued which returns a 'requestID'.  The 'getResponse' method is then called which is suppose to return the value of the property.  When the VI runs it throws a 'System.NullReferenceException' error.  The VI and the .h files are attached.  Thank you so much
