I have version 2.2.8.1 MSSQL. Installed on a FullTrust 2008 server.  I am moving it to a 2003 MediumTrust server.

I have everything moved over and the site works, but when I go to log in (PW stored hashed/not recoverable) I get the following error:

Server Error in '/' Application.
Security Exception

Help?

All but the App_Data change... is that really required?
