Help with org.jawin.COMException please!

I'm having trouble working with a simple COM DLL.  I ran it through the
Jawin Type Browser and generated the classes (IValidateLogin and
VAlidateLogin) I needed but when I try to create an instance of the
interface I get:

org.jawin.COMException: 80040154: Class not registered
 at org.jawin.marshal.GenericStub.win32Invoke0(Native Method)
 at org.jawin.marshal.GenericStub.win32Invoke(GenericStub.java:66)
 at org.jawin.win32.Ole32.CoCreateInstance(Ole32.java:109)
 at org.jawin.DispatchPtr.<init>(DispatchPtr.java:63)

 at com.orametrix.suresmile.scoring.ScoringApp.<init>
(ScoringApp.java:68)
 at com.orametrix.suresmile.scoring.ScoringApp.main
(ScoringApp.java:98)


I registered the DLL by double clicking on it before I ran the JTB.  I also
made sure that the java.library.path was set correctly.

Here is the code I tried:

try
    {
      User32.MessageBoxW("Test", "Jawin");

      Ole32.CoInitialize();

      IValidateLogin iLogin = new IValidateLogin(IValidateLogin.DIID);

      String[] retArray = new String[20];

      iLogin.ValidateLogin("User","Pass","Domain","Server",retArray);

      System.out.println("Made the call OK...time to inspect the array...");

      Ole32.CoUninitialize();

    }
    catch (Exception e)
    {
      e.printStackTrace();
    }


The messagebox comes up just fine, but the application crashes when the
constructor for IValidateLogin(IValidateLogin.DIID) gets called.

The JTB created the DIID value, so I would think this is correct.

What is it that I am doing wrong?

Obviously I'm new to Jawin, so please don't assume I've done anything
correctly other than install Jawin (the samples work just fine).
