.Net Blaze Webservice Exception

Difficult to diagnose this without access to the code, but here are the things I would investigate:

It looks like it is failing in the process of creating an instance of the project to execute.  Does the project compile in Blaze Advisor Builder?  Are all the paths to the object models and repository correctly formed?

Is this failure happening with the generated code from the Quick Deployer?  Were you able to use the deployment directions to get the runner code to work prior to encorporating the client code into your own architecture?

If you look at the code in "A", can you find where in the code it is throwing a NdServiceException in order to determine exactly where in the process it is failing?  You can use debugging to step through the deployment code until it gets to the point of failure to narrow down the failing call and better determine what is not configured properly.
