IIS7 - Object reference not set to an instance of an object
<p>I have a website that I get the below error on whenever I navigate beyond the default.aspx page.</p>

<p>My issue is that when I run in debug mode via VS08 I do not get the error and when I run the code on a Webserver running IIS6 I do not get the error.  However, when I run my site on my development box against IIS7 I get the below error.  Also, I am running my IIS7 site out of C:\inetpub\wwwroot.  So I don't know how I could get the error in my C:\Users\ folder.  Finally, the method get_profile() has not existed in my code for over 2 weeks. </p>

<p>I have tried rebuilding the solution after deleting my .dlls, I have cleared IIS7s app pool, restarted it, restarted my computer, and redropped the entire folder contents from my development folder 5 times.  Nothing has fixed this error. What do I need to do?</p>
