NullReferenceException

I'm having some trouble setting up a windows mobile project and I'm hoping somebody can help me out. I've followed through the tutorials on the website and in the help documentation with no luck. I guess I have two issues that are probably related. When I get to the line in the function startRoute() that says "nMan.SetGps(new GpsSimulator(nMan.Navigator.Directions, 2));" I get a NullReferenceException. It looks like it's saying nMan.Navigator.Directions is null.

Also, if I comment this line out the program runs but where the mapCtrl should be, there is just a gray box. The code I'm using is below. I've made a few changes from the tutorial for debugging purposes but even if I copy the code right from the tutorial I get the same result. Any help would be appreciated..

Hi Nathan, maybe the error is on the Repospath variable you don't have to specify the name of the gbfs File. You only have to put the folder of it. If the path is on "\\Storage Card\" you should change the Repospath=""
