FileBot

Hi Guys,
I have a Server with Ubuntu 14.04 LTS and i installed the gui XFCE.
I installed Filebot and after i click on load to select the files that i want rename is Freeze so I need to close the session from X2GO and reopen but i can't go far from this.
What can be the issue?
Thank you in advance

Have you tried using drag-n-drop instead?

I tried and is working but next action freeze all.

No clue. Try google. Make sure you're using the latest Oracle JRE.
