Some are saying to turn on auto-updates, quit the game, shut off the console, and wait a few minutes. When you turn it back on it, it should be updating in the mean time, but I haven't tried it myself. There's a couple saying after putting in standby mode, that it will turn it self on to update and then off. Again, haven't tried this myself, but it's a solution a few suggested on the main forums and had a decent amount of replies saying it worked. Edit* This did work for me. If it won't update, toggle the auto-update option, turn it off and wait 5 minutes. Turn it back on and hopefully you'll see 99% Installing for FM5.
