I have waited the 24 hours you tell me, I have contacted your CS over the phone, I have waited 48 hours. My card works for everything else. Works fine on Origin. And I still get error NU2001.
WHY? If this isnt a problem on your end. Then, when my current sub runs out, I wont be buying a new game card.
Please give another call to our phone support and mention that you have done all the advised steps. The agents will look into this issue further for you.
