These are the instructions I used:
1. Clear your system cache on all drives; flash, HDD, etc.
2. Disconnect from the internet on your console so you don't have a network connection
3. Open your system settings and edit the data/time of the console by going to Console Settings > System > Clock and change the time. Note: it will only allow you to change the time to your own manual time if you are disconnected from Xbox Live. Then change the time to 11/22/2005 1200 AM.
4. Now restart your console.
5. Once the system is back on let it reconnect to the network and Xbox Live which will update your time to the current time based on your time zone.
6. Once you do this and your system is back on and you are connected to Xbox Live, start the game and it "should" let you connect to EA Nation again.
I didn't have to clear any cache.
IT WORKS..You cant start a team, but you can join friends online and do challenges!!!
