It's a common exception that means your code is trying to access/reference an object that has not been instanced, and it's a null object that doesn't exist in memory.

You are also being told where it is happening the exception. You need to use the debugger and set a breakpoint in the class method and single-step until it blows up and use Quickwatch to find out what object on the line that threw the exception is null. You find out why the object is null.
