Yesterday, I wanted to play online "Gears of War 3" with a friend by unity, when i open the menu "conect unity" the screen stays loading, on it appears a message which says "downloading feed data" and appears a rolling circle, and it doesn´t load, it only is happening since yesterday, because i had played before and I have hadn´t any problem, in fact, just in that morning i was playing for a while and when i started the xbox in the afternoon, the problem appeared, and today when I tried to connect to unity, it worked, but i didn´t play, so, i turned off the console and a few moments later i turned it on the problem remains. besides I have one friend and he has not any problem ever. any solution?
postscript: Also I have the pingpatch on and the devlink off.
