As you can see by the stack trace, it's getting an error when trying to authenticate the user. I recommend setting a breakpoint to determine what's going on:

1. Open your project in VS .NET
   
   
2. Click the Open File button and open the ..\Mere Mortals Framework 2003\Mere Mortals Framework\Managers\mmUserManager.cs file
   
   
3. Set a breakpoint at the top of the AuthenticateUser() method
   
   
4. Run your application and step through the method to see what command is being sent to the back end

If you are not able to hit your breakpoint, check out the MM .NET Dev Guide topic "Stepping through MM .NET Code in the Debugger".
