Dear Ozan,
Can you please try the following:
  • Restart MATLAB
  • Before opening the Cluster Profile Manager, change your MATLAB locale using the following command run at the MATLAB Command Prompt:
 >> java.util.Locale.setDefault(java.util.Locale('en-US'));
  • Now open the Cluster Profile Manager.
This is a known issue that we fixed, but sadly the fix didn't make it into R2014b.
Kind regards,
Dan
