That's bad news. I tried to start the JVM again with the following 
snippet:

| jvmSettings |
JNIPortJNIInterface libraryFile: 'C:\Program 
Files\Java\jre6\bin\client\jvm.dll'.
  jvmSettings := (JVMSettings new)
 			name: 'JVM with ghost class generation';
 			yourself.
  jvmSettings usesGhosts: true.
  jvmSettings jniPortSettings useJNIHelperLibrary: false.
  jvmSettings runtimeSettings classpath: 
'.;C:\Users\Levi\Desktop\SQUEAK\Squeak4.1-win32\JNIPort.jar;C:\Users\Levi\Desktop\SQUEAK\Squeak4.1-win32\JNIPort-Tests.jar'.
  Cursor execute showWhile: [JVM newWithSettings: jvmSettings].

But it crashes:

Current byte code: 98
Primitive index: 1060

Any ideas how I could start it without crashing?
