IsaViz 2.0 doesn't work with dot.exe from GraphViz 1.14 (Win XP)

Hi,

I just installed IsaViz 2.0 and GraphViz 1.14 on my Win XP Pro Sp2, set all the preferences correctly, and then tried importing the examples from the export dir (ms_7.6_1_r.rdf, etc).  Below is the error reported in the log.  

I fixed this by downloading a more recent dot.exe (11-Sep-2004 02:40  568K) from 

http://www.graphviz.org/pub/graphviz/CURRENT/?C=M;O=A

BTW, if there's another way to report this error please reply.
Thanks.
Larry
