I have been unable to purchase anything through the Origin interface since Dead Space 3, as all of my attempts at purchases have been denied due to 'error NU2001'
Origin themselves couldn't help me and the automated responses I got from them stating it had now been fixed try again were fabrications as I still had the problem, in the end I just gave up trying to buy anything from them, as have the countless thousands of other people who have had the NU2001 problem (You can verify this with a quick Google for 'error nu2001' - No wonder they are in trouble now, they have lost a huge cross section of their customer base through lack of communication between the complaints department and management. The only person who has genuinely tried to help me with this problem so far is whomever it is that runs the Origin Facebook page - Thanks Dude! I haven't had problems prior to or subsequently when purchasing stuff through Steam or GOG, or anyone else for that matter, so the problem is with Origin, not me, my card, nor my financial institution. So, I can't even buy SC5 through Origin to join in the fray, or not.
