I was getting the error, tried everything on the boards and i Googled it a bit. Didn't help. What did work, on my end, was to set everything to "vanilla" in the Nvidia control panel. Just for this game. It's worth a try?

Go to your library click on property select launch options pick direcx10/11 and launch the game,wait a few seconds and it should work again

I've been trying for the past few hours to get Civ V to launch, i'm stuck at updating the executable. I guess either 2k or Steam screwed this up for us? Super bummed...

Installed the latest NVDIA driver and now it looks like a windows do crash when I load a save file. Just me?

I can't play Civ V from the launcher anymore. Everytime I try the game loads but the screen is just black with the resource icons flashing. If I come to Steam and "verify file integrity" it always finds 3 corrupted files and downloads them. Then if I click the Play button from the Steam window it runs fine until I exit and next time repeat....
