For those of you having issues playing all the new Xgd3 titles after the silent update the other day here is a workaround that is confirmed as working. Please understand we are not responsible for your xbox getting banned, catching on fire, growing wings, killing your ps3 ect…
I took a standard usb flash drive.
1 First format it in your xbox (if you have not already done it)
2 Put it in your pc
3 Download Horizon (search google for horizon+xbox360)
4 Download latest update from here http://www.xbuc.net/
5 Drag the update you just downloaded into Horizon and it will copy too usb drive
6. in your xbox go to system settings => Memory => Hard drive. Press “Y” for Device Options and then last Clear System Cache
7. Start the game, it will ask you to download the lastest update. Accept it and now it is working online again
8. Every time you restart the game (meaning shut down the xbox or just go to the dashboard you have to repeat step 6
It does work..
