I did find a fix! After many hours of frustration. Try this..

- Press the Xbox guide button from the dashboard and go into the settings blade. Then account management and download history. Select the AFL pack and then download again. It won't actually download again but I think it resets the licences properly.

After I did this everything should be back to normal. Good luck!

I had read your post on google about the problem you experienced with your AFL Legacy pack. Your situation is the same one as mine, Xbox breaks, get a new one, transfer all licenses and it wont work. Im just wondering if you had found any fix at all for this as I am having the same problem and am looking for a solution. Any help would be greatly appreciated as I just signed up so I could finally get a solution from someone
