OK, I missed something pretty big, I'm still getting the same error, but I missed a couple things that change a lot of the assignment so I'm going to repost the code here now as I have it. I still have the same errors, you're right though, I had main all messed up. I probably still do, but looking at a couple of the class things, I'd say it's a lot better than it was. Still something is missing though and I'm not sure what.

The problem is your initialization at the beginning of main. I can't fix it cuz I'm completely lost as to what you're doing w/that, but it has to do w/your struct initialization--it's incorrect.
