"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

The only part of this error message that is relevant is the inner exception. I've cleaned up that part of it. The error is a null object reference, and the Stack Trace shows where it is occurring in your code. Start setting breakpoints on the referenced lines and figure out which object reference is null.
