not beeing able to open a port usually means you dont have the right to do so. maybe you have firewall software running - or you dont have a privileged account. other than that i dont know what exactly causes the problem within maya - i dont see that error when i boot up maya. maya should try to listen to that port - after i open maya this port is open.

and dont worry to bother too much - only because you are new to maya does not mean anybody here will rip of your head
