This is kind of a delayed question but i bought Honest Hearts on May 18th for Xbox platform at a friends house, cause i don't have internet a my house. I was able to play the entire dlc there but when i went back home the dlc no longer worked, It says that the downloadable content is corrupted, which stops me from playing the dlc. I decided to go back to my friends house and re-download it, but the same thing happened, where i was able to play hooked up to the internet but not offline. Ive waited obviously awhile for an update to this problem. the dlc was great but i really want my monies worth, is there anyway of fixing this problem, i have bought all dlcs up to date, and do plan on buying Lonesome Road. Can anybody help

You need to download the latest update at your friends house it should be fixed if not well...

Same thing happened to me with Dead Money, I still haven't figured out why.
