I'm having the exact same issue!
I don't know I pulled it off but I was able to get the game to recognize my keystrokes/ mouse in multiplayer, simply buy selecting the "battlefeed" located on the little blue bar that pops up when loading a multiplayer map, I then could change the settings from windowed to fullscreen and could play.
However, this issue is still persisting in single player, I load the campaign, watch the stupid little 8 second intro, then when it says "hit enter" I spam the key and nothing happens, then it loops back and forth. if I minimize the window I can't bring it back up and thus have to open my task manager to close the program.
this is incredibly infuriating. I basically spent money on a game that's only works "sometimes". and to top that off...whenever I try to play multiplayer (or single player) I get a pop up telling me to upgrade from AMD13.4 to 13.9, IM USING AMD. 13.11 BETA, WTF EA?? get your act together please.
I'm getting that same message regarding the drivers as well, but I have the latest drivers for my video card. People are posting new questions every minute, so it's tough to get an answer as people are just bombarding these guys with new questions.
I installed Windows 8.1 from Windows 8 and the problem was solved, I also have cloud disabled on Origin.
