mobility calculation fail

I am trying to calculate carrier mobility in black Phosphorous, with atk 2015.rc2 , I am getting error in the electron-phonon coupling analyzer and the other results show

What is the problem?  Script attached.

You say there is an error - what error?

We will generally not provide any support for issues in 2015.rc2. All users must upgrade to 2015.0, where many issues already are solved.

Ok I will try run in 2015 and get back to you.
