Error: Activation cannot proceed. (R2014b)

Question

I have installed Matlab 2014b on a node of a cluster but failed to launch the software ( matlab14 is an alias to /usr/local/MATLAB/R2014b/bin/matlab):

root@trunks:/usr/local/MATLAB/R2014b/bin# matlab14
  MATLAB is selecting SOFTWARE OPENGL rendering.
  root@trunks:/usr/local/MATLAB/R2014b/bin# ---------------------------------------------------------------------------
  Error: Activation cannot proceed. You may either:
  1. Set an X11 display, and restart the activation process
  2. Use the silent activation feature
  3. Activate using the license center

While prior to that I had already activated, sucessfully:

root@trunks:/usr/local/MATLAB/R2014b/bin# ./activate_matlab.sh -propertiesFile /home/users/khue/Matlab/R2014b/activate.ini
Silent activation succeeded.

I tried for another user (not root) with a different license file but still failed.

Thank you in advance for any suggestions.
