Give it all you got, I can't even begin to answer whether this product does work with DGDK.NET, I don't have it, so I can't say whether it does or it doesn't.
My only recommendation is to either wait for someone else who CAN answer your question, or risk the purchase and use the standard model exporting facilities. You could email support@thegamecreators.com and see if they can respond with regards to knowing if the product is compatible with the C++ DGDK toolkit, because if it is, then it will work with DGDK.NET as well.
Sorry I couldn't help you any further.
Paul.
