Game crashes loading into the game at a certain point every time

[Sarkus]

I've had Civ 5 since launch but sometime last summer it stopped working. What happens is that it crashes while loading into the game. So I get through the opening movie and all of that, choose which mode I want to play, and while its playing the voiceover for the particular civ I've chosen I see the loading icon at the bottom flash a few times and then the whole thing crashes back to the desktop with a generic "experienced at problem" error message.

I spent a little time trying to figure it out last summer and discovered that if I ran the Steam verify integrity utility it would tell me one file was messed up. Then it would reload the file but the game did the same thing. Running the intergity utility again would lead to the same result. Checking around the common solution I was told would be to delete the game and reload the whole thing. As my internet connection is not all that fast, I was not in a hurry to do that.

Just the other day I decided to to the full reinstall but it did not solve the problem. I've tried the support solutions on Steam, which mainly involve running the vcredist, dxsetup, and d3dinstall exe's. But that doesn't do anything either. I don't see anything in 2k's official support section that seems to match this issue.

My OS is Vista32, SP2. Like I said the game ran fine up to a point last year and I have no other games with any issues.

One thing I did notice that went away at some point was the DX9 vs DX10/11 option. It simply does not show up on the menu when I load the game. Unfortunately I cannot remember when I noticed that. I did change out my video card about a year ago from Nvidia to ATI, but as far as I can remember the game worked for a time after I made that change.

Any ideas?

Actually, I've just gotten it to work but I'm not sure what is going on.

After trying a lot of other things I created a new user account on my PC and launched it from there. As a completely new game it automatically defaulted to different settings, including a different resolution then the 1920x1080 of my monitor. The game launched fine.

I then went back to my normal log in and changed the resolution. Now it works.

I don't really understand why the game worked fine until last July but suddenly won't work with a supported resolution.

My video card drivers are up to date, by the way.

Well, if DX11 is greyed out/not working, they you changed a setting on your PC that corresponded with the issue

The DX10/11 option isn't greyed out, though at some point last year (after one of the patches) the option stopped showing up everytime I launched the game. When I was messing around trying to get the game running earlier I fired off the both the DX11 exe and the regular exe from within the Steam folder and the game crashed in the described way both times. When I fired off the regular exe it did ask me which version I wanted to run and DX10/11 was not greyed out.
