Well I've recently had the internet set up in my new house and for some reason when I try to play multiplayer or even singleplayer 9 times out of 10 it keeps coming up with the message "Download content could not be accessed. Please reconnect storage device if removed"... Thing is, the game was working perfectly fine whilst I played it offline, but now this ?

I don't know if this is part of the problem, but I played some of the tracks that I hadn't even put times on whilst offline and now I've come back on it still saved the medals but not the times, could that somehow of corrupted the game ?
