I was going to buy the throttle components for the rocket an decided to save before I spoke with Old Lady Bishop. I spent all of my caps on the component and I ended up killing the old hag along with her pack of dogs. I went to load up my save so I wouldn't lose my caps and I get this message: 
 
This save game relies on downloadable content that is no longer available. Continue loading?     
 
I clicked yes and received another message. 
 
Storage device unavailable. 
 
I checked my saves from other games and they're fine, not to mention that the hard drive is built-in.  
 
Have any of you had this problem?
 
I could either start a new game or send it back to Gamefly.
