issue with running ajax(click and script) in controller

Hi,

I am using load runner 9.51 and created test scripts using Ajax(click and script) and it executed fine in VuGen.

But when i executed the same scripts in controller through performance center 9.51, i am getting error "
you don't have license for this user type"

DO i need to have ajax(click & script) license to run in controller through performance center?
