David,

Thanks for your help. I did end up creating a new project and adding all the items from the previous project a few at a time. It is working now. The funny thing is that I added every item that was in the old project to the new and did not have the error come up once. I think you were originally correct in that the error was not too indicative of the root problem. I have a feeling I may never find out the real problem.
