Webware for Python

I can't get AppServer to work on my WindowsXP box.  I had it running fine on my old Windows98 box.  On running AppServer it appears to start up properly but then the first request to a page never returns and gives the following error in the console: 
  
       1  2004-03-27 16:20:06 Traceback (most recent call last): 
     File "WebKit\ThreadedAppServer.py", line 293, in threadloop 
       rh.handleRequest() 
     File "WebKit\ThreadedAppServer.py", line 501, in handleRequest 
       dict_length = loads(chunk) 
   ValueError: bad marshal data 

Any ideas what the problem might be?  The full startup output is included below. 
  
Thanks 
Ben
