In the Origin app, right-click on the gear icon next to the Play button and select "Repair".
I had this problem too, but running a "Repair Game" fixed it.
I'm having the same problem of the infinite loading screen. I can start the game and it will play the opening screen, but after that it freezes for a while, changes into a totally white screen and the music starts playing, what can go for hours, so I believe it's not just delay. There's nothing except white on the screen and I can't even close the game for as much as I try. I've tried running "Repair Game" for about more than 10 times but it never really works on anything. After the update (november 10) the game would crash occasionally so I had to save regularly, now after the patch, (november 18 if I'm not wrong) it won't even load. I'll keep trying to run the repairs meanwhile, but I'm not sure if it'll work.
