Had this problem too. The cause in my case was the the Raptr app (AMD Gaming Evolved client), which uses an ingame interface and prevents Origin's from working.
THANK YOU terminalDe, after reading through all the old posts, i skipped to the end to find more recent posts and bang! raptr was indeed the issue. Probably the same reason I couldn't access origin ingame with ME3 or sim city as well though I haven't tried either yet, I'm sure those should work now. big thanx man, this was driving me bananas and I.m a crazy old coot as it is....I don't need to be any crazier lol.
