Answer 1

put the @Html.AntiForgeryToken() inside your form

Answer 2

Might want to take a look at this question. The anti-forgery cookie token and form field token do not match in MVC 4

It is possible that this is a timeout issue. Basically when the timeout happens the cookie is not stored because the iis user that the site is running under does not have the proper access. For me I changed the application pool to load the user profile and this seemed to fix it.
