SF4 AE PC: Buttons don't work

I dled the game from Amazon and installed it. When I ran the game it worked but none of my buttons worked, including my keyboard, mice, and my joystick. I couldn’t “Press Start” when the screen prompted and I couldn’t even skip the beginning intro movie. I know my keyboard works cause I could Alt+F4 out but I couldn’t no buttons work ingame. Anyone else have this problem? Anyone know a fix?
