Had the same issus. When I disabled my SLI i Nvidia controlpanel I was able to Launch the game. So If you have SLI disable it.

Cannot start game after re-downloading complete CoD verifying files tried everything.

I get the orange gunsight and desktop back ground.

And thats all.

I've read around that you have to disable SLI globally.

Bug: Hurricane engine temps too cold for engine start up.

Hurricane MkI 100 Oct: oil temp starts at around 16'C (although one trial oil was 12'C on spawn), engine wont start until 20-21'C. Method for starting engine was spamming ignition until temps reached 20-21'C oil, 40'C water. Radiator was closed; mixture auto rich; prop 100% (tried different % but made no difference); throttle 15% (again tried different settings, 15% worked well once temps got to near 20'C as prop would spin for longer).

Also, weird bug on ATAG: a/c sunk through the ground when attempting a take off and was damaged.

Ship "dots" appearing through clouds.
Hatch cable in 109 does not cast shadow. (minor bug)

Joystick not working anymore....
 

My joystick Saiteck X52 don't work anymore under Cliff of Dover since the beta patch.
The trottle work but not the joystick.
I have tested under windows and my joystick is fine and work well.
I've checked tje conf.ini and the joystick is enabled, I've checked the inputs and axis are well defined.

So can't test the awsome improvements of Cliff of Dover thanks to the last beta patch!

Mixture is still reversed in Hurricane Mk1 100oct; I had to move mixture to the forward (auto lean) position to enable a smooth running engine with Boost Cut Out Enabled.

I agree with Bounder ref the low temperatures preventing engine start, once Glycol had reached 45 degrees (ish) from constantly trying to start it, the engine would finally start.

Thank you devs the hard work, overall a very positive opinion of the people I know (nice new colors, great visibility, smooth gameplay, no 1 fps, etc.), but there are some serious bug (collected from Hungarian forum):

a- Already mentioned, the mixture in the RAF planes. I can't setting before flight, and most of the RAF planes can't start on the ground.

b- (Hubabacsi) He 111 flew without Tail (He lost the elevator and rudder, but he can landed with aileron and throttle only):
(maybe it's important, i was used the R.A.M. gun of the Su26 when these bug appears...)

c- (102.VO_Herr_LacAI) The Hurri can fly and landed after a 109 blew up half of the wing:

d- I notice, hard to land and start from ground with Su-26, because the gear sink into the ground. During landing is causes blow-out the tire.

In my opinion too much did the intensity of the lighting in the daytime from the lamps lighting in the cabin + lighting from the exhaust.
In the past beta-patch everything was fine during the day, evening and night. In the final best to return as it was, than they are now, but now it is overkill.

mixture control not working on ground start
 

tested with Spit I, Ia, IIa
tested with all possible/available key- and axis-settings
tested with info-window showing throttle, pitch, rad, and mixture values

air-start: mixture works as expected. Lever moves on key, axis, and mouse click and move. Info window shows correct values.

ground start (engine off): mixture never worked. Lever never moves, info-window value never changes (neither on key, axis, or mouse click and move). Got engine up and running anyhow and flew around for 7 minutes. Mixture never started to work.
