After a new fresh install, I log on as admin and edit the Home page.  When I save the changes the below error message is displayed.  However, it does appear to save the changes first since reloading the home page shows the changes.  Could there be a setting somewhere that I need to change to prevent this from happening when I edit pages?

My web host is a medium trust, MSSQL 2000, running .Net 2.0 on IIS

Server Error in '/' Application.
--------------------------------------------------------------------------------

Security Exception
Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

Exception Details: System.Security.SecurityException: That assembly does not allow partially trusted callers.

Source Error:

The source code that generated this unhandled exception can only be shown when compiled in debug mode. To enable this, please follow one of the below steps, then request the URL:

1. Add a "Debug=true" directive at the top of the file that generated the error. Example:

<%@ Page Language="C#" Debug="true" %>

or:

2) Add the following section to the configuration file of your application:

<configuration>
<system.web>
<compilation debug="true"/>
</system.web>
</configuration>

Note that this second technique will cause all files within a given application to be compiled in debug mode. The first technique will cause only that particular file to be compiled in debug mode.

Important: Running applications in debug mode does incur a memory/performance overhead. You should make sure that an application has debugging disabled before deploying into production scenario.

Do I need to delete all previous files from the host and upload everything all over again, or is there just a few files that have changed that I can upload?  If at all possible, it would easier to not have to upload 9000+ files again if there's just a few that need it, but can certainly do so if needed.  What is the best way that you recommend?
