Ben - 2012-11-27

I am trying to do survival analysis, but cannot successfully run either Kaplan Meier or Cox Regression.
I am using windows 7 64 bit machine, with MeV 4.8.1. Java is JRE6 of 32 bit under Program Files (x86).
It seems there is some issue of R, either in getting files, or in writing files. I pasted the error information below.
I tried to run MeV as administrator, and also disabling firewall, but it did not seem to help.
Any suggestion will be highly appreciated. Thank you.
