0. run arma 2 once (get to main menu and then quit). now do the same with operation arrowhead.

1. open arma 2 install directory (e.g C:\Steam\SteamApps\common\Arma 2)

2. cut all the shit inside ********

3. paste all that shit in to your arma 2: operation arrowhead addons directory (e.g C:\Steam\SteamApps\common\Arma 2 Operation Arrowhead\AddOns)
(if AddOns folding no is exist make plz)

4. in steam games library window, right click arma 2: operation arrowhead -> properties -> general tab -> set launch options
enter in
-nosplash -skipintro -winxp


5. this should have combined the two games. test this works by:
	5a. launch arma 2: operation arrowhead from steam
	5b. click multiplayer
	5c. make sure you're browsing internet games, not LAN (bottom left of screen)
	5d. click filter
	5e. type 'ccg' in host, click ok
	5f. order results by mission
	5g. join one of the Chernarus ones, e.g "customcombatgaming.com Wasteland - Chernarus 2"

	if you can spawn, it works.
	(errors starting with "No entry 'bin\config.bin/..." are expected)
