I cant play halo 4 downloaded content

On halo 4 since the last spartan ops was released I have not been able to play any downloadable content. That includes all of spartan ops, every map pack and now forge island. I tried re downloading multiple times but it does not work. It just reads player failed to load content every time I attempt to play. How do I fix this?

First is the DLC for the account you play on>

Second try clearing your cache for the harddrive

third make sure the license for said content is registered to your xbox.

Fourth download all the content again and make sure its on the HHD

Finally load up halo 4 and check if it fails do load the content call up Customer support because you most likely have a hardware issue
