I seem to be having difficulties loading our StreetMap Premium data license. As a result when I attempt to call a method to open the Network Dataset I'm getting a response of:
Unable to open dataset. Error Message: Exception from HRESULT: 0x80040221

I believe this is translates to:
FDO_E_NO_OPERATION_LICENSE -2147220959 The application does not have the required license for this operation.

I have run the sdlic file we were provided with and looking at ArcGIS Administrator it appears to have registered:

Name:	license.jpg

I am currently using a License Initializer that is a part of the VRP sample which can be found here. Will this retrieve the data license? Do I need to add something to load the license? Does it matter that we are not using Desktop at all and just Runtime Engine?

Thanks again for your assistance.
