Jperf Question

[<And...@st...>]

Hi.  I finally got Jperf running on my WinXP box, and all was working
beautifully until this morning.  The Jperf software runs, but the bandwidth
and jitter graphs will no longer appear.  At the end of a test that is setup
to automatically have the graph pop up, I get one of the following two
errors in the DOS window in which I started Jperf:

Prior to this morning (no system or network changes btw), the graphs worked
just fine for any test that I ran.  All the jar files are in the same
directory as iperf.exe, and I start Jperf with the following: 
 
java -classpath Jfreechart-0.9.6.jar;Jcommon-.7.2.jar;Jperf.jar Jperf
 
 
All images are in the directory, all the source code, the binary,
everything.  
 
I've tried running this on Java SDK 1.4.2, 1.5.0 beta II, and JRE 1.5.0
beta.  None work now.  
 
Can anyone tell me what I'm doing wrong, or if I'm missing something?
 
Thanks in advance
