My GT5 was freezing often while loading cars so I decided to delete the game data and reinstall it. Now, whenever I load up the game and enter 'GT Life' some options are greyed out, some are simply not there, and the cursor can't be moved - in fact, the only thing I can do is press the PS button and exit the game. I've had this problem before: the solution was deleting the data, cleaning the disk and then trying again. This time, however, the solution failed. Before the glitch happened a second time I hadn't done the full install ('Pre-install Files'), so I did that before entering 'GT Life', to no avail. No idea what to do now. The internet connection is disabled, if that matters.
