ok, i've installed zope 2.0 on my win 98 machine (i've run zope before on this machine). when i start the server with start.bat, it seems to run fine. however when i go to access it through my browser i get the following error:
 

Zope Error

Zope has encountered an error while publishing this resource.

IOError

Sorry, a Zope error occurred. 

Traceback (innermost last):
