Hello,

How are you launching the game? Through steam or through the steam commonapps folder?

If you're using steam - make sure you use "Launch Combined Ops", if that doesn't work you can try manually starting the game as Administrator.

Generally this is fixed by running steam as an administrator.

And this is explained in the wiki already...
