When trying to access the default users page I get the error pasted below. 
All the other modules appear to work fine. Can someone please suggest a 
fix -- this module is an important learning tool.

Thanks,

Andrew

When  access ThePhile, you have to get to it through 
http://localhost/ThePhile which will get you to the default.aspx under the 
root ThePhile.  The cast problem is caused by your having not been 
authenticated by the system.  Read carefully about the SiteIdentity part 
of the book.

I have just finished the book and I think it's a wonderful book.
