FIXED IT ! for me !
I have win 8.1 . Same pb problem like you guys and i just fixed it very easy: DEAKTIVATE Origin Ingame for BFBC2!
(right klick on your game in your library and "game-characteristics..." and make a hook on "Disable Origin in the game for this game".)
That solved my ...pb corrupted file/memory [85000]... issue. And I also used the method from #rugburn11 and set DirektX from "auto" to "9". And now my bfbc2 is running perfekt like back in those days :D nice and thanks
