Flintoff11

I have been playing the game for several hours but recently noticed that I haven't seen the logo for the auto save. Wen I press start to try and manually save the game, the "save game" and "load game" options are greyed out and I can't select them. Is there anything I can do? I'm dreading the thought of returning to the main menu and losing hours and hours of gameplay. Please help. I purchased the European (England) version today and installed the update upon request.
