Here's a thought:
Apparently there's a similar problem on the PC version and the fix is to install the toolset. No idea how that affects it but perhaps there's something in the code that allows the server link? I know it's a long shot but it's frustrating to not be able to play a backwards compatible game with or without the discs. I have the discs but it is still being sold on the Xbox Marketplace so it really should be fixed.

What toolset? because I have all 3 games in the DA series and Inquisition & 2 won't work. Origin does but the DLC don't show up
