Ok I read all of the other topics about this problem but I have no luck with any of the Solutions. I have all the DLC's for New vegas and I usually play it online. I did a system cache clearing and for safe measure re-downloaded the Title update#5 before going offline. Now when I started the game offline the DLC Old world blues is apparentley corrupt and does not load. I have tried many solutions to no avail so can I please get some help.
