I have a cable modem and i connect behind a personal router. i have opened the correct port and made sure that i dont have any other sort of firewall on. However, i still cant connect. I click the connect button in the fire menu and the red light flickers green and then returns to red. please help this is annoying. When i first got the program i was able to connect. When i restarted my computer then i wasnt. A hasty response would be appreciated
