Until yesterday, I normally played some games through Games for Windows - LIVE. I tried to play Gears of War with my friend, but we weren't able to connect each other, so I was looking on the internet for some solution and I find that I should try to restart my router, so did I. Now I can't login anymore, I always get the "The LIVE service may be unavailable or there may be an issue with your home networking equipment or firewall." I didn't change anything in my router, I just restarted it like I did many times, and I never had a problem with anything else. Now I install Games for Windows - LIVE, restart my router and this crap get screwed... The funny thing is, that when I disable UPnP in my router so I login again. The problem is, I don't want to have UPnP disabled, because then my downloading speed is slower, and it's better to leave it enabled anyway. I tried everything. I fowarded ports, restarted my router again, reinstalled Games for Windows - LIVE, connected to internet through the cable (i'm on the Wi-Fi), I also reseted my IP adress and router settings and also disabled my Windows Firewall. I'm really tired of this piece of crap service, I trying to fix it the entire day, still no luck. I never had any problem with this service, until yesterday... By the way, my IP adress and UPnP in Games for Windows - Live keeps saying "Not signed in." When's my UPnP disabled, so my NAT Type is moderate, but i can login. When's my UPnP enabled, so my NAT Type is open, but i can't login, wierd... I appreciate any help, thanks.
