Because ever since the Sir Hammerlock DLC came out, I keep getting the message to download the compatability pack when I start up the game, and yet I have it on the flash drive I have my gamertag/profile on.
Also, I can't access any of the DLC at all unless I redownload it, save for the Gearbox weapons and the artifact gotten from the Mechromancer Pack
Note: The message stopped appearing and the DLC started working again once I redownloaded it. --- "You're dead if you aim only for kids. Adults are only kids grown up, anyway." - Walt Disney
Microsoft and Sony charge thousands to patch games so maybe this is gearboxs way of getting around that. I agree a patch wouldve made more sense. --- "Reality is merely an illusion, albeit a very persistent one" Albert Einstein
