Forza 5 needs an update

I can’t seem to get my console to do the update. It starts doing the update then says there is a problem. All my network is fine as I can play COD online for instance. Any ideas?

Unplug your console then start everything up?

Tried that 3 times and no luck :-S

Uninstall the game and reinstall it?

followed by

Reset your gamesave?

Reinstalling it will only take about a million years! But that might be what is required. Is there a way to manually download an update?

Is this the car pack as well?
