Beginner in CAElinux – problem while giving run

Hello

I am beginner for CAElinux and linux as well. I do have 10+ years experience on commercial FE software.
I am trying to learn CAElinux and following “piston tutorial” available on www.caelinux.org/wiki/images/7/74/Piston_tutorial.pdf

I have loaded CAElinux on USBdrive after lot of struggle.

While following “piston tutorial”, I am facing problem when I am giving run. (Page 15/24).
On gui screen 'Object Browser' in front of 'Linear-static' I am getting “<f>_NO_COMM_FILE”
I checked in working directory and found file is there in working directory.

I understand this might be very basic question, however I am trying hard to resolve it.

Can anyone help me in this.

Thanks & Regards
Suhas
