I've reinstalled Windows 7 64 bit and my new origin client I just downloaded wouldn't let me log in to it. So here is a quick workaround for this - download older origin client version (i used latest beta), then disable internet and install it. After you'll get to Origin "log in" window, enable internet, enter you password and press "log in" button - that's it. If you have trouble following instruction - just watch this video - it should help.
