Has anyone tried deleting the dlc and reinstalling? Would that cause previous saves to be lost?
The error is on the marketplace. All that would do is waste your time. Seriously, is it that hard for people to grasp the simple concept that it's a glitch in the system, and Gearbox and Microsoft are working to fix it?
No kidding, the pack was glitched and didn't work correctly, this is purposeful so no one downloads the bad version.
