config problem

With Isaviz I have the following problem with importing:

one of the example rdf files:
----Importing RDF-----
XMLManager.parse(C:\IsaViz\tmp\isv60466.svg): java.lang.IllegalArgumentException: No attributes are implemented
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

my own rdf file:

-----Importing RDF-----
RDFLoader.load() com.hp.hpl.jena.shared.JenaException: rethrew: {E301} The prefix "rdf" for attribute "rdf:ID" is not bound.
Please verify your directory preferences (GraphViz/DOT might not be configured properly), your default namespace and anonymous node prefix declarations

I have installed JDK 1.4.0 and graphviz 1.10 (CURRENT) and configured the proper path. Isaviz.cfg is stored on a networkdrive:

<?xml version="1.0" encoding="UTF-8"?>
<isv:config>
    <isv:urls/>
</isv:config>

Also the default base URI is set to blank.
I seem to have gone through all the installation instructions...

What could be wrong?
