Unable to add "Handler Mappings" for the Workflow site created

Hi All,

I have a set up which has both the “Dev” and the “Test” environment in the same machine.I wanted to have workflows for both the instances.So 1st i configured WF for the “Dev” environment and then duplicated the WF settings for the “Test” environment (with the help of the steps in http://workflowax.wordpress.com/2009/09/17/running-multiple-aos-on-the-same-box-all-using-workflow/)

I did all the steps correctly and when i tested it prompt me an error saying

when i tried to add the “Handler mappings” it again prompted me with an error

3162.WF_Handler mappings error.bmp (300 KB)

Please someone help me to solve this issue.
