Not able to use the PDE toolbox

I am a student of IIT Delhi which has academic licences of version 15b and 6 user licences for the PDE toolbox. I have gone through some tutorials on using the PDE toolbox for solving 3D finite element problems. But i am getting error messages in the prompt on trying to execute any command (like createpde or pdetool) related to the tool box as shown in the image attached. Please suggest the possible reason and the way out.
