I was having issues but I think it was my Xbox because I started having issues on other games where the whole Xbox would just turn off. Had no issues until I started playing CFB 26 and even had the thermal paste and cleaning done and that did not fix it. The whole system would turn off not even a crash to the dashboard.
Ended up buying a new Xbox and getting rid of the old one, but I am hesitant to play CFB 26 and the whole system turn off again. It sucks because I preordered the game and spent $70 on it when it came out. I have posted a couple other forums but it has pretty much been radio silence from EA or my replys are lost in everyone else's and I can't see them. I had no issues playing CFB 25 and have no idea what the issue could be.
