Hello, so recently I obtained a new xbox (my old one broke.). I had the Dawnguard DLC on my save. I haven't been able to transfer the license yet as my gold membership ran out.
You can transfer your licences without needing a Gold account. Also, if you haven't done that yet, you can still play you DLC content, so long as you are connected to XBL as they have one of the two licences.
