Missing Map Pack Maps

[sinnott18]

So I went to play BF3 today and when I went to the server browser it won't let me play any of the Armored Kill, Close Quarters, or Back to Karkand Maps. I have all the weapons and assignments for these map packs, (I'm a premium member so I downloaded all of them) but whenever I go to play on one of these maps I get an error saying this "disk is unreadable." I downloaded my friends disk on to my Xbox, and the problem still occurs. I tried to re-download the map packs in the BF3 store and they download, but they don't appear in my storage. Any idea what's going on or how I can fix it?

Can you play other games on your Xbox after receiving that error in BF3?
