Place the Data folder in "C:Program FilesSteamSteamAppscommondawn of war 2GameAssets" or your installation directory if different.<br />

You also need to have the -dev command added to the end of your game shortcut so it looks like this where "C:Program Files" is your game directory.<br />

"C:Program FilesSteamsteam.exe" -applaunch 15620 -dev<br />
