I can't play newer games on my Xbox 360 when signed into live. The console is less than year old. Games like F1 2010, Ghost Recon 1 & 2 play fine but newer games like Far Cry 3, Halo 4 won't play on Live. When signed in, the game is recognised & top left
box says 'play Halo 4' for example but when click to play get message saying clean disc. The newer games are fine when not signed into Live. The older games are no problem at all.
