Ok I had the problem of my loading screen just infinite looping, and my most current save corrupting. This is what I did to try and play again -

• Remove NV patch
  
• Clear System Cache
  
• Start game
  
• Repatch game
  
• Load earlier save

Ok so remove the NV patch by selecting it and deleting off your HD, then back out to the point that you can clear your system cache. Once cleared log back onto NV and re-dl the patch (this should be the only patched game now) then load up an earlier save... this fixed my infinite loading screen, and luckily only my top save (which was only ten minuets of work) was corrupted and it let me play again. I already shut off my Xbox again and loaded it back up by going to load (this seem to be important because continue still freezes) and playing again :intergalactic: this is not 100% fool proof since I could only try it myself so if others could try it would be awesome!
