command line for generating reports

I'm using the CMDRunner.jar to generate reports.  For example...

java -jar c:\apache-jmeter-2.10\lib\ext\CMDRunner.jar --tool Reporter --generate-png Images\%~n1_ResponseTimesOverTime.png --input-jtl %1 --plugin-type ResponseTimesOverTime --width 1000 --height 800 --granulation 100

However, when I run it, I get an error that it "Could not access C:\apache-jmeter-2.10\lib\ext\lib".  Any thoughts on why the path is getting modified with an extra "lib" on the end?

Thanks,

Glenn
