Now Windows 7, new CPU (i5) and motherboard, and RAM.
And the same problem...

It's mistique. I have re-installed Windows 8.1 totally (uninstalled the game, uninstalled Steam, formatted disk D where my games were, formatted disk C, installed Windows). After this I didn't install any programs which could conflict with BA. I didn't install ANYTHING except video driver and Steam....

If it helps, there are some logs from the Process Monitor and sfc /scannow.

Can you try removing the game entirely and reinstalling?

Nothing helps.

What is DEBUGMODE?

As for the window mode, it doesn't work. I remove "Fullscreen" in launcher, but game starts in fullscreen...

Try deleting the OPTIONS.TXT file in My Documents/My Games/BBCBA to see if that helps. Or indeed try renaming the entire BBCBA folder.

It didn't help. In both cases a new BBCA folder appears.

It happens when I end deploying and click "end turn".

Unfortunately it didn't work.
Very strange. Why does this error appear just now, after over 6 hours of playing and several missions?!

I've installed the latest AMD Catalyst. As for my videocard I can't find any drivers at all. You can see it on official site: http://www.asus.com/Graphics-Cards/HD7970DC2T3GD5/HelpDesk_Download/ I've downloaded DX9 from the same source as Yours. Do You think that this http://steamcommunity.com/app/1...

That's it.

Unfortunately it tells that dx9 requires windows xp or another old system...

pipfromslitherine wrote:Yep - perfect. It looks like an issue with your graphics subsystem. Do you have DX9c installed? Are your video card drivers fully up to date?

Windows 8.1 - DX11. Do I need DX9с?!
Windows informs there is no need in updating videodrivers...

Where can I find logs? Is it here?

Steam version.
Mission "HOLD THE PASS" (Desert Rats).
I've finished deploying units, pressed "End turn" and... got this.

How can I solve this problem?
