Hello! My name is Crosswire, I'm a huge fan of fallout, played the first games on the PC and played Fallout 3 to death. I've had Fallout New Vegas for quite some time now, but recently got the DLC from a friend due to the fact I do now have Xbox Live (as I cannot afford it)

I have all the DLC Including:
-Dead Money
-Honest Hearts
-Old World Blues
-Lonesome Road
-Courier's Stash
-Gun Runner's Aresenal

Sadly however upon loading the DLC I found that only Dead Money and Courier's stash were working. The other DLC's were not taking effect. They were marked down on the main menu but it's like the game wasn't recognizing them. I don't want to lose my level 30 character, but I experimented and tried a new game. I had the same issue, only the Dead Money and Courier's stash DLC's were active.

Does anyone have any suggestions on what I should do?

Notes:
-The game has a tendency to freeze when searching for Downloaded Content when I try to to "Continue" instead of load as well as when I quit the game and return to the main menu.
-I cannot delete the DLC because I have no way of re-downloading it. A friend of mine ported the DLC to a flash drive and I transferred it over to my Xbox.
