OK, I just found out Azureus is giving me an NAT error, so I went in my router settings thinking that somehow I switched off my port forwarding... but no, everything was fine. I haven't installed anything lately, and I even tried rebooting it in safe mode. Anything else I can try? I'm out of ideas
Try Unplugging your router and modem and leave it for about 5 minutes. Also its possible that your ISP Provider has blocked those ports. But that'* a rare occasion. Try changing ports...but remmember to do the port forwarding on your router. I also use Azureus and have experianced this problem.
