Here's the scenario:
-My Live account is not the account on which TES Dawnguard was installed on my Xbox.
-I installed Dawnguard onto my Xbox with the primary family pack account, and played it on my own account.
-It worked for a few days.
-Today I decided to move downstairs, taking my save files and profile with me.
-I move my account and save files onto a USB, insert the USB into the port on my downstairs Xbox, and moved them onto that console.
-I start up the game.
-DLC doesn't work, despite having been moved to the USB with the rest of the files.
-I look online and find that the account that installed the DLC has to be on the same console as the account you're playing it with.
-I look, the primary account is shared between both consoles.
-I sign into the primary account and reinstall the DLC to the hard drive.
-I start up Skyrim.
-DLC doesn't work.
-Give up, decide to move back upstairs.
-Move Skyrim files and profile to the upstairs console.
-Start up Skyrim.
-DLC doesn't work.
-Give up, decide to consult a forum that knows infinitely more about this sort of thing than I do.
Tell me what I'm doing wrong. Or, if it'd save space, tell me what I'm doing right.
