I am about to have just about every error on my 360, or better said my 360s.
My recent inconvenience is having my 360 prompting for an update for every game i put in to play, even though i just updated it.
And it keeps doing so.

The solution to get rid of this is to clean up your 360′s cache.
To do this, go to your Dashboard, System , Memory and then Hard Drive.
Highlight the drive and press Y for the options.
Now press X, X, LB, RB, X, X.
Now confirm the system maintenance and follow the steps on the screen.

This will clear all your updates, patches, addons and so on, but it will not damage or remove your game saves.
Once the process has been completed, restart your 360 and download again the maps, addons and whatever you might want.
Note: You should be able to “download again” all your updates, maps and games extensions without having to pay for them.

This is the fix that stops this issue (or bug)….or whatever this is.
