TruClient issue

Hi all:

I created a TruClient Ajax FireFox script to run a Tableau Report app. It works perfectly on VUGen and also when I run it in Controller with localhost as load generator. But it fails when I try to use one of my remote load agent machines. 

This is the message I'm getting inmediately I kick off the scenario:

Error -205177: Unable to obtain mdrv result dir: sVerify=C:\Users\perfqa\AppData\Local\Temp\brr_AKT.684\netdir\c\temp\failuregenerator\log, sGroupId=NULL, sVUsers=NULL, sProductName=NULL

Inmediatly, the virtual user runs to Fail status and the scenario dies. I need to clarify that I never had this issue with my other scripts (HTTP-Web or Web Services). 

Did any of you see this before? Any help will be appreciated.

Thank you.

Rodrigo.
