problem launching D2W assistant on Windows

Hi, 

I am not able to start the D2W assitant in a D2W Web application.

Here is what I am getting in the console:


NullPointerException
  at com.webobjects._eoproject._WBInterfaceContext.initWithProject(_WBInterfaceContext.java:142)
  at com.webobjects._eoproject._WBInterfaceContext.<init>(_WBInterfaceContext.java:84)
  at com.webobjects.directtoweb.D2W.activateWebAssistantServer(D2W.java:356)
  at com.webobjects.directtoweb.D2WActions.openWebAssistantAction(D2WActions.java:26)
     ... skipped 4 stack elements
  at com.webobjects.appserver.WODirectAction.performActionNamed(WODirectAction.java:144)
  ... skipped 9 stack elements


and in the error page:

I am starting the application from eclipse and I am working on Windows 7.

Anybody aware of this problem and a potential solution?
Thank you,
