How to unblock origin

Blocked origin when I was playing sim city 3. Now I cant download or login to origin to play BF4 legit. Im stuck in offline mode. Anyone know a fix?
Answer #1
did you block it with your anti virus and/or firewall? Normally you should be able to go online (same way you went offline). Otherwise take a look at this thread. http://forum.ea.com/eaforum/posts/list/8897332.page;jsessionid=4B9A508B3353E2598638EED0B8BE8C71
