Hi, just downloaded the game with gods and kings off of steam, and having an array of problems. Random crashing, always crashing on city attacks, and now the game crashes on the loading screen for certain save files. I'm on windows 7 64 bit. I can also only play in dx9. My graphics card is a ati mobility radeon 540v, and dxdiag says I have dx11, but clicking the dx10,11 option when starting the game results in nothing happening. I think I have the latest drivers for the card, but I can't find any for it newer than 2010. I've tried reinstalling the game, the drivers, checked that compatabilty mode isn't on, nothing. Trying to start from CivilizationV_DX11 under steam apps gives me the message that d3dx11_42.dll is missing. I'm also only guessing that playing on dx11 will fix any of the crashing problems. Any help would be greatly appreciated
