Stefan Duelist

I am trying to use ygopro-1.033.5-b-Percy-linux-full on a Ubuntu 12.04 LTS 64bit machine and I can't start a duel with the AI or a multiplayer duel using either join or host.

If I try to duel the AI no action occurs when i click the start button and no log or error is shown in command line.

If I try to play a multiplayer duel I can't see anny room in the list and if I try to host a room I get a unable to connect to host message and again no log in the command line.

Thank you for your time.
