Yep but didn't get the whole list....then I removed the mod to use the Xbox 360 pad and now I do not get the error anymore but still the DLC does not show on my profile on Bioware Social (I re-bought Levianth) however I am now going to do the first mission on the normandy and see if I get the other message from the Admiral related to this DLC.
I do hope it works, I love ME and I did not play it back in the days as EA was even worse than now (I do not pirate games so I did not play it even in that way).
What's the point of all this DRM when I am paying for the game....their politic is a joke and Origin is a joke too, it does not work even in offline mode as Steam does....
EA will never change unfortunately, I hope they will go caput pretty soon as they ruin the industry...
