something you did wrong
 

must be something you did wrong than, works fine for me and im win7 ult 64bit
u sure you installed the patch correctly? if you don't get a red box on start up it means you did something wrong. did you perhaps put the two folders in your 1C folder in your documents instead of in the steamapps folder under your steam folder in the program files? its got nothing to do with DX if your running 11 which everyone is unless your using XP which your not obviously. than DX isnt your issue, perhaps if you installed the patch right are you using any beta drivers for your graphics card that might be causing an issue? I rememberd I had to uninstall the 310.xx graphics drivers for my GTX460, despite working in CoD it kept on freezing up my Shogun 2 fall of the samurai.
so idk if you any of these are your issue or not. but my advice if it still doesn't continue to work, is to just re-install the game, get the patch, and extract it to the right folders, delete your cache and start the game and it should work fine, if you see a Red square at start up it means you did it right.

HorrorRoach....what graphics card do you have?

I have the same problem as the OP. Tried everything and it will not start. So far i dont even know what the game looks like after the patch. :(

If i check integrity after failed try and the game reverts back to latest official patch everything works fine.

Make sure you delete your cache folder before you extract the patch.

Trust me, iv tried everything, twice. Including doing a fresh install of the entire game, witch btw takes forever on Steam. :(

You name it, i did it, catch folder, turning of firewall, fresh install, downloading patch from 3 differant sources, callibrated my monitor, made a fresh pot of coffe, noting works.


No worries though, either it works all of a sudden or i just have to wait for the officiall version.


Last tip iv found was to lower the settings from high to medium or low (no i havent forgotten to set the same res in the orginal game as my monitors naitive res) on the fresh install before patch since that, apparently, can make it go belly up. Should probbably make sure to feed the cat before patch, just in case. :)

After I installed the patch it crashed on me 3 times before I could even join a multiplayer game, but then on the 4th try it just sort of magically worked.

Make sure you try to launch it a couple of times before changing something.

OP I think you're misunderstanding what DirectX is...

The patch being incompatible with DX9 just means it won't work for video cards that can only run DX9...

DirectX is an application programming interface that, in simplest terms, tells your hardware what to do when displaying images. The software you download on your computer when something requires DirectX will always be the most recent version, in this case DX11, but your hardware will only run at its maximum capable.

If you have a dated video card, like a GeForce 8600, you're stuck at DX9, a GTX 250 can run DX10 and DX9, a GTX 580 can run DX9, DX10, DX11 applications.

Cliffs of Dover has utilized DX10 for its best graphic settings and features, but to keep their audience wide as possible they've included a "DX9 mode" for people that don't have advanced video cards. This "DX9 mode" is automatically applied for people that cannot run the DX10 features...in this alpha patch that you're trying to run, DX9 is disabled, therefore anyone that cannot run the game in DX10 will not be able to run it, no matter what they do, except get a newer video card.

Revert back to the current version of CloD that is on steam if you wish to play the game right now. You can do this easily and quickly by right clicking Cliffs of Dover in your steam library>properties>somewhere in there is a "verify local game files" that will revert the patch.

Will try it when i reinstalled the game, thx.

I had this same problem (CoD started, but always crashed before showing main menu).
I deleted conf.ini and then the crash was gone. Thanks for the tip!

Also try editing conf.ini to launch the game in windowed mode (fullscreen=0 and lower resolution). Start game, change back to fullscreen mode via game menu, restart game.
