Does this still work? i've tried it a few times and theres nothing happening, no mesage
Just google, ''How to clear you cache''If it's dlc you want to remove, go to memory and delete it... if its an update delete your cache, like I said google it.
Just so you know, you can't play online unless you have the latest patch.
