My friend and I both went and bought retail copies of GoW3, and have been trying to get them working on our modded 360 consoles. Google told me we would need to manually apply a system update, but I tried downloading that from Xbox.com and can't get it to load (I assume because I'm already up-to-date. The game simply displayed an E66 error. I flashed the console back to stock, and it makes it seem like the game will boot, but the disk image never shows up and when I hit play game, I am disconnected from live, the system hangs, then am booted back to the dash. Is there something I can do to get this working?
