Access Denied error when run loadtestrunner

Hi,

I am using non-Pro SOAPUI 4.0.0 on Windows 7 32-bit. SOAPUI itself works, but when I try to run loadtestrunner from the UI, I got this error:

I was able to work around the problem, by starting SOAPUI with "Run as Administrator", but I'm still curious which file it's having a problem with? I've tried setting the soapui.log to allow for everyone, but still get the same error.

Thanks,
Jim
