I can't get the win2K version of 2.0 to work, using GraphViz dot.exe v 1.14.
I can see a graph of the sample project that ships with the editor but I
can't parse any new files, whether I'm importing them or pasting them into
the Quick Input view. It doesn't matter whether they're RDF/XML or
N-Triples.

If I try and Replace the following file (from the online RDF Validator) for
example:

<?xml version="1.0"?>
<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
  xmlns:dc="http://purl.org/dc/elements/1.1/">
  <rdf:Description rdf:about="http://www.w3.org/">
    <dc:title>World Wide Web Consortium</dc:title>
  </rdf:Description>
</rdf:RDF>

I get the following error message:

-----Loading ISV project-----
-----Importing RDF-----
XMLManager.parse(C:\IsaViz\tmp\isv6479.svg): org.xml.sax.SAXParseException:
Element type "null" must be followed by either attribute specifications, ">"
or "/>".
RDFLoader.load() java.lang.NullPointerException
Please verify your directory preferences (GraphViz/DOT might not be
configured properly), your default namespace and anonymous node prefix
declarations

Can anyone help?
Thanks,
Howard
