Is JRE installed? Are you using the AntiX firewall that is denying certain hosts to run.
At SPM, JRE 4.9.2-10 appeared to be already installed. I reinstalled it, but it didn't help. Firewall is off.
I am not a online gamer so I won't be of much help on this.
Is there any way to download the game and then play it offline? I downloaded the swf file, but I don't know how to play it.
