Forum:Fatal DLC problem (Xbox 360)?!

Hey all. Ive recently been playing Call of Duty: World at War for a few weeks now. Seriously, its only fun online. However, my internet's down for the next few weeks. So i put Fallout 3 back in.

I tried to load my most recent save. However, a message pops up saying "This save relies on content that doesn't exist. Some objects may be bugged or missing. Continue loading?" I haven't loaded it from fear of corrupting my file.

What the hell's going on? I have ALL FIVE DLCs. They show up in my Xbox's memory files. How do they suddenly dissapear?

I have the most recent patch. Any advice is appreciated. And NEEDED. Thanks.
